The act of fast paced
anal pleasure, then a sudden
removal of the penis (or other tool) from the anus. The outcomes are usually rather spectacular, as shit literally hits the fan (and everything else in its path).
enjoyed with 2 or more people.
Frank: Hey man, I heard your wife
let you try anal with her the other night. How'd it go?
Dave: I pulled
out too fast, and shit went flying
everywhere, last time I try that..
Frank: aahh, the Plunger Effect
