In text slang, OPT most commonly means “optional,” indicating that something is your choice rather than a requirement. Depending on the conversation, it can also refer to opting in or opting out of text messages, and less commonly, “Other People’s Thoughts” when discussing opinions online.
Because OPT has several meanings, the surrounding conversation usually makes it clear which one is intended.
Example:
Friend: Movie night is opt if you’re busy.
You: Thanks! I’ll let you know later.
What Does OPT Mean in Text?
The slang use of OPT usually comes from the word optional.
Instead of typing the full word, people shorten it to OPT in casual chats, gaming groups, school discussions, and social media messages. It’s a quick way to let someone know there’s no obligation to do something.
For example, if someone says an event is “opt,” they’re simply saying attendance is your choice.
Example 1
A: We’re playing after work, but it’s opt.
B: Cool. If I finish early, I’ll join.
Example 2
A: Cameras are opt during today’s meeting.
B: Nice, thanks for letting everyone know.
Example 3
A: Homework review is opt tonight.
B: I might still attend.
Sometimes OPT appears in conversations about subscriptions.
For example:
- Opt in = choose to receive updates.
- Opt out = choose to stop receiving updates.
These aren’t exactly slang, but they’re very common in texting and digital communication.
Finally, some internet users use OPT to mean “Other People’s Thoughts.” You’ll occasionally see it when someone asks for opinions.
Example:
“Just sharing my OPT—not trying to start an argument.”
Although this meaning exists, it’s much less common than optional.
Real Chat Examples
Friend: The study session is opt today.
You: Perfect. I’ll join if I finish work.
Snapchat
Friend: Face cam is opt tonight.
You: Good, I wasn’t ready anyway.
Instagram DM
Friend: Want to post together?
You: Sure! Filters are opt though.
Gaming Discord
Friend: Voice chat is opt.
You: I’ll probably just type today.
Emotional Meaning & Tone
Unlike abbreviations such as LOL, OMG, or SMH, OPT doesn’t express an emotion by itself. Instead, it signals choice, flexibility, or permission. The tone depends on how it’s used in the conversation.
Friendly Tone
When someone says something is opt, they’re usually trying to remove pressure.
Example:
“You can join us if you want—it’s totally opt.”
This sounds welcoming and considerate.
Neutral Tone
Most of the time, OPT is simply informational.
Example:
“Attendance is opt this week.”
There’s no hidden meaning—it’s just letting people know participation isn’t required.
Supportive Tone
People often use OPT to make others feel comfortable about saying no.
Example:
“Bringing snacks is opt, so don’t worry if you can’t.”
Here, the speaker is being thoughtful rather than demanding.
What Does OPT Mean From a Girl?
When a girl uses OPT in a text, it almost always keeps its regular meaning: optional.
She may be letting you know there’s no pressure to make a decision or join an activity.
Example:
Girl: Dinner is opt if you’re tired after work.
Meaning:
She’s giving you the freedom to decide without making you feel guilty.
If she uses OPT to mean “Other People’s Thoughts,” she’s usually inviting opinions.
Girl: I’d love everyone’s OPT before I decide.
What Does OPT Mean From a Guy?
The meaning is generally the same.
A guy might use OPT when organizing plans, gaming sessions, or group chats to show that something isn’t mandatory.
Example:
Guy: Mic is opt tonight.
Meaning:
Using voice chat is optional.
If referring to Other People’s Thoughts, he’s likely asking for feedback.
Guy: What’s everyone’s OPT on the new update?

It isn’t offensive, rude, or considered inappropriate.

Common Mistakes & Misunderstandings
Because OPT has more than one meaning, it’s easy to misunderstand if you ignore the context.
Assuming It Always Means “Optional”
While optional is by far the most common texting meaning, OPT doesn’t always refer to choice. In discussions about messaging services, it may refer to opt in or opt out, and in some online communities, it can mean “Other People’s Thoughts.”
Confusing “Opt In” and “Opt Out”
These two phrases are opposites.
- Opt in means you agree to receive messages, newsletters, or alerts.
- Opt out means you stop receiving them.
Mixing them up can lead to confusion, especially when dealing with marketing texts or subscriptions.
Using OPT in Formal Writing
Although OPT is common in casual texting, it isn’t suitable for every situation.
For example, in a business email or school assignment, writing “optional” is usually clearer and more professional than using the abbreviation.
Assuming Everyone Knows the Abbreviation
Not everyone is familiar with texting shorthand. If you’re talking to someone who doesn’t use internet slang often, spelling out optional avoids unnecessary confusion.

- Optional – The most common texting meaning, indicating that participation is a choice.
- Opt In – Giving permission to receive promotional texts, emails, or notifications.
- Opt Out – Choosing to unsubscribe from marketing messages or alerts.

- Optional Practical Training (OPT) – A U.S. immigration and education term for eligible international students. This is unrelated to slang.
