The swagger that one acquires after consuming enough alcohol to give them a extra super confidence and euphoria. This is mostly associated with the morning after a long night of heavy drinking when the drinker still has that superman confidence till the buzz wears off.
Brian had that drunk swag, he got like 2 numbers and fucked a bitch in the bathroom the next morning at school.

Jamal liked working the mornings after a long night of drinking cause he had that drunk swag for a while, which made him feel like a king.
