look up any word, like dirty sanchez:
Buxin out is when you make plans with your pal and he won't answer his calls or texts and avoids you for at least a month at a time.
Guy 1: So me and Jim are gonna hang out tonight.
Guy 2: Really? When?
Guy 1: Lets call him. <ignores several calls and texts>
Guy 1: That rat bastard is Buxin out!!!
