Best Diet Buddy.
People you beat the shit out if they eat.

Me and my BDB enjoy to practice our techniques by puking on each other during break.

BDB

A nine inch angle grinder, a Big Dangerous Bastard. So named because of the number of serious injuries associated with the use of these machines. Banned from many worksites because of this.

"Hey, get that BDB off this worksite ! Nothin bigger than seven inches here without half an hour of paperwork."

BDB

Braindead Bitch — A savage insult used to describe someone acting ridiculously clueless, oblivious, or downright toxic. Usually reserved for people who consistently make dumb decisions or say things so absurd you can’t help but facepalm. Perfect for calling out those wild TikTok comments or everyday nonsense with zero filter. Often paired with the 💀 (skull) emoji to indicate you’re dead from the stupidity.

“She said pineapple belongs on cereal? Total BDB 💀.”
