Airhump makes a gun go off

[toeprint]

I'm looking for an gif icon with the above description. It's definitely a sideways shot of the body (not sure if it's zoomed in on the lower body, or a full length shot) and when he arches up, the gunshot is seen. It's looped so it's a continuous hump and shoot.
Bonus: What is the source of this gif?

Thanks for any help in solving this.
