But me writin' a verse would be the only way they buyin' a bar
White boys used to trip and send me over a gin

from Childish Gambino – L.E.S. Lyrics on Rap Genius

Meaning

Gambino has said before “vodka for my ladies, whiskey for a grown man"—he earns his fans (and his women) through his talent and only through his talent.

White boys in the bar trip over seeing him, and they also “trip” up by sending him a gin. Gin and tonic is the whitest and preppiest drink. Ever

Even though these white boys trip over seeing CG, they only buy him a drink—they don’t buy out the bar (i.e. cover the tab). When they buy his songs, which are full of bars of music, that’s the only time they buy the bar
