The smell that comes from the "Gooch" when you sweat/drop a fat duce.
The best way of experiencing The bouhj is to take your pointer and index finger, rub the Gooch firmly then inhale strongly threw the nose.
"DUDE you gotta check out this bouhj stank, its massive!"
"NO man thats gross leave me alone"
-sneak up on them then shove it in their nose (or if your feeling fiendish, their mouth)-
