Did you hear about Willem Dafoe using a stunt hog in "Antichrist?" Apparently his hog was too big for Lars von Trier's vision, so they hired a stand in to make it more realistic.
To flex; show off. Look up the 90s term "Flossin"..."Stunt on these hoes" could be "Flossin these hoes", which is a line in a Biggy song. Basically an updated version of this.
Watch dis imma stunt on these hoes! Dis bih ain't wearin no drawz! Call da Hilton fa dat prezidential suite...12 bottles a Cris.
