To move in an impaired way as a result of being intoxicated. Could be stumbling, crawling, or a slow jog to the bathroom.
"So then I squabbled up to Jen and spit some mad drunken game at her at the party." or "I was strugglin', I barely squabbled to the bathroom before I threw up."
But are you squablin' though? Usually uttered as two pseudo-toughs urge the other to start hitting when both are too afraid to begin in the first place.
