An act of cupping ones hand over their own butthole, and farting into the hand, to later trap the gassiest stench while simultaneously whipping your hand out with great efficiency and speed to carefully keep the horrendous stench in your hand, then placing the hand under a poor unsuspecting target’s nostril. The stench will instantly travel up the nostrils and the sensation will smack the brain. Hence the term brain smacker
He brain smacked me.
He grabbed his fart and brain smacked me.
Brain smack means to catch your fart in your pants then throw it in someone’s face

Here pal, let's get down to smack generator. I've got cracking swag from that last burglary I did. Maybe get enough for a £10 bag of smack.
