Rost: Dude, you just destroyed the bathroom!
Rhett: Yeah, I committed Guinnesscide last night. Sorry

Bailey: Barkeep, I'll have a Smithwicks.
Barkeep: Sorry, but a bunch of kids came in here and committed Guinnesscide. But we have Bluemoon.
Bailey: Fuck Bluemoon

Rhett: When did Drew get so drunk?
Rost: He committed Guinnesscide a while ago.
Rhett: But he's drinking dirty Shirley Temples?
Rost: Yeah, but he had like ten Irish Car Bombs earlier.

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."

Breadhead 

Someone who is addicted to obtaining money and building wealth. A money addict and fanatic. Breadheads often work more than one full-time job, and some even participate in illicit activities to "obtain the bread".

A breadhead is like a crackhead, but for money instead of crack.
