Jack Pack
A Jack Pack is when a guy tries to act tough like a shack pack but ends up being a total fag. He thinks he can handle a whole bottle of cheap whiskey and still walk straight.
Jack tried to be a man. He drank 12 shots. Now he’s puking in the rec room.
Jack Pack is just a guy named Jack who thinks he's tough.
Jack Pack tried to drink me under the table. He ended up crying in the laundry room.
