What Does OT7 / OT8 / OT9 Mean?
OT stands for “One True.”
It basically means “I love the whole group.”
In Korean fandoms, this is called “얼빠 / 올팬 (all-fan / all-member fan)”,
but in English-speaking fandom spaces, OT7 / OT8 / OT9 is more commonly used.
The number after OT refers to the number of members in the group.
- OT7 → supporting all 7 members
- OT8 → supporting all 8 members
- OT9 → supporting all 9 members
For example:
- BTS has 7 members → fans often say OT7
- Stray Kids has 8 members → fans say OT8
Why Do Fans Use This Term?
1. To avoid comparing members
Some fans have one strong bias.
Others simply love the group as a whole — the chemistry, the teamwork, the story.
If you don’t want to choose or compare, OT7 / OT8 / OT9 is a way to express that.
2. To show “group love”
It’s also used to express full-group support.
For example, someone might say:
“Jimin-biased, but OT7.”
This means: “Jimin is my bias, but I love all the members.”
Many fans start with one member…
and then one day realize:
“Okay… I love everyone actually.”
That’s the OT moment.
Use OT7 / OT8 / OT9 in Your Social Media Bio (Copy/Paste OK)
Here are simple bio lines you can use.
(These examples are for BTS, but just switch in your group!)
- Bias: Jimin | OT7 always ✦
- Yoongi is my bias, but let’s be real… OT7.
- Bias: Jin. Behavior: OT7.
- OT7, but SUGA owns my heart.
