You also have to use some acronyms when you are posting in group pages
OT – Off Topic
In conversations with other Kpop Fans, you will notice some acronyms too:
Bias – the member of an idol group who is your favorite
example: Sehun is my BIAS in EXO (it means Sehun is my favorite member in EXO)
UB – Ultimate Bias – same as the meaning of Bias but with a stronger degree. It means the member of an idol group that you super love and even if you have other favorites, that member is still your number one.
example: Sehun is my bias but Tao is my UB. (it means Sehun is my favorite but Tao is still the best for me)
OTP – One True Pairing. I means the pair (consist of two members) that you like together.
example: Tao and Sehun are my OTP. I love TaoHun a lot. (means I like Sehun and Tao together)
For EXO Stans, there are acronyms that you have to know:
OT12 – Just like OTP but with a twist. Because EXO members are twelve, OT12 is created for them. OT12 means when the twelve members of EXO are together.
example: I have an OT12 poster of EXO. (means I have a poster of EXO where the twelve members are together.)
OT6-K – Because EXO is divided into two groups, OT6 is made. OT6 means the six members of each group is together. OT6 K means when the members of EXO K are together.
OT6-M – OT6 M means when the members of EXO M are together.
EXO’s trend words meaning:
Yehet – came from Sehun. It mostly means Yehey. He says this when he is happy.
Ohorat – came from Sehun. It mostly means Alright.
Kaeb Song – came from Baekhyun. The word came from Akaepta which means regretting something or something wasteful. Kaeb Song has three different meanings for BaekHyun.
Meaning 1: when you feel like something is regretful.
Meaning 2: when you say something funny but it is not interesting.
Meaning 3: It also means Sorry.
These are the list of things I know so far. I will update this post when I learn something new.
