Neheehee

The type of guy who will make you fall for his sparkling personality. Making you become his "bestie". Making you believe that the two of you are best friends, and that he cherishes your friendship. One day will try and convince you that y'all are meant for each other. That you're the loved of his life. That he wants to wife you up and meet your dad. Only to f you see k you over and make you realize he's a pathological Liar, narcissist who will break your heart.

I knew this dude. He was a nicolASS, a neheehee.

Cheeks 

An Irish phrase meaning shit, derived from ass
(Not to be confused with the literal description of one's buttocks)

"Did you hear the song Aylek$ dropped?"
"Hardly. Her music is absolute cheeks."

"My boyfriend say LaFlame is cheeks."
"Tell your boyfriend I said it's his mixtape that's cheeks."
