(adv/adj) Denoting work undertaken by a bro for the good of one's bro without
compensation, esp. when that bro needs help moving,
a ride to the airport, or even a temporary wingman. Such work is considered just as noble, or perhaps nobler, than other
voluntary service.
(adv) I do kinda have
something else broing on tonight, but after I rackjacked Ted last night, I feel like I have to throw him a brone and help him hook up with Robin pro brono.
(adj) Might I enlist your pro brono services,
gentlemen? This Tijuana
prostitute isn't going to bury itself!
