1 definition by Vin Winey
A term used in rejoice of a great moment or action, usually followed by a head movement, like a nod.
If you were to get laid, the next day in the pub you'd walk in, say "bulba" to your friends and do the head nod, they would then do it back to let you know they've recognised your feat.
