Gracks

When you lick your finger and rub it under someones nose making their upper lip smell like stinky saliva breath.

My breath was so bad I gracks attacked my little sister and she threw up.

Gack

A stretched wide pussy that looks like she accidentally spilled a warm pie all over her lap. It is could also be used as a vacuum cleaner to suck up the entire universe if needed. Anything that fucks that Gack most likely be terminated from inside. Watch out because once you go Gack you don't come back.

Guy 1: Bro... don't go near ashley

Guy2: oh shit why...
Guy 1: because she's got a gack i could see her sucking up people a mile away.
Guy2: oh shit....

Gackt

The worst insult someone may get. It's a combination of every single bad words and insult in the world. If you are ever named a Gackt, better think about how your life is turning out and how you should end it.

"Omg you're so Gackt"

"Geez you sound just like Gackt, but worst"

"you Gackt"
