Rares Moment 

To say something that makes no sense and is incredibly false.
Realizing something 10 minutes after everyone denied it and said the opposite.

Person 1 : Yo your account got hacked.
Person 2 : No it isn't, i play on it right now.
*After 10 minutes*
Person 2 : Oh wait, i got logged out and I'm playing as guest. I really got hacked...
(Person 2 had a "Rares Moment" of realizing)

Person 3 : We need to decorate the class tomorrow for the 8th Graders, the other class will decorate for the 9th Graders.
Everyone else : You stupid, everyone decorates both classes.
Person 3 : No, y'all wrong.
*After 10 minutes*
Person 3 : Wait, it really everyone decorates both classes...
(Person 3 had a "Rares Moment" of saying false things)

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."
