childcore
When someone is acting like an immature little bitch, entirely blasé and callous about everything and with an air of superiority that only an adolescent could portray in a non-satirical manner. Typically attempts to belittle other people for no reason, spouting things like "dadcore" and "nerd" with little justification.
I asked Shogunner a question and he responded like a childcore little bitch, saying things like "lmao" and "wow m8 u r dum." I slapped him on his face and he started crying like a pussy ass bitch!
