Cai

A kinky bastard who will get triggered if you tell him that. He is very nice but is into a lot of freaky things. He is an extroverted but case who is liked by a lot of people because everyone thinks he's ridiculously attractive. He makes bad puns that become infectious, this is how he charms his way into poor humour. He seems normal and nerdy at first but no...

I met this guy and thought he was alright but he turned out to be a Cai!

Cai

A dumbass who cheats on every girl he meets and only uses girls for their looks. He is also really childish when it comes to relationship. Always wants to have sex and doesn't give his girl a break smh. Also has a very small d*ck. Break up with him if he treats you in a wrong way, or stay with him if he's alright and a sweet person because not all Cai's out there are rude or mean.

Cai has such a small pp.
