When you say goodbye to a friend who is leaving on his bicycle, and when he isn't looking, you pull out a shotgun and stealthily shoot his rear wheel.
Person 1: On my way home i noticed that my rear wheel was empty. I also had several bullet holes in my back.
Person 2: Haha! The good Ol' Baghdad Buckshot.
when you ejaculate and hold your foreskin to keep it in there, then get someones attention and proceed to start urinating whilst still keeping your foreskin closed and it bursts on them like a buckshot
my boyfriend called my name so i went in the room and he did a dirty buckshot, it was so disgusting.
To perform a backshot, you gotta screw somebody from behind, bareback. either hole will do. Now, when you pull out instead of blowin it internal-like, and jizz on her back, THAT'S a backshot.
A good one will hit her hair, a great one will hit the far wall.
Watch any generic white peopleporn, and I'm sure you'll get a great example in no time.
