The act of first putting on a winter jacket, assless chaps, and a bandana place firmly around the penis (on a male). First you have to meet a rabid penguin named Larry, fuck him until his asshole falls off and your nut sack turns into slippery mush, hense causing your cum to blast off on Larry's left ass cheek, hence called the swamp launcher.
Larry: What the fuck?

Me: sorry.. premature ejaculation.

Larry: Why is there cum glazed on my left ask cheek.?

Me: Well, Antarctican Swamp Launcher.. BITCH ASS NIGGO
