look up any word, like blumpkin:
The act of eating out a man's anus while simultaneously giving him a foot job (stimulation to ejaculation through friction generated between foot/feet and penis). The act is accomplished by having the man sit on the face of the person giving the sneaker snacker, while his or her legs wrap around the man's body to administer the foot job aspect.
I was giving this guy the ol' sneaker snacker when my hamstrings cramped up on me, and I had to give up.
