Yosemite slam 

The act of sneaking in two party popper pistols into the bedroom and shooting them off when the man cums scaring the girl after pulling out and finishing on her back so the confetti sticks to her.

Yah bro I gave my girl a real Yosemite slam last night I think she still has it stuck to her back.

Canuck Roll

Diving toward the ground and rolling up to one knee to shoot at the enemy. As seen in many movies & video games and realistically a poor tactical move.

I did a sweet canuck roll to avoid the gunfire and take out the bad guys.
