Snakeskin Slap
The act of responsibly using a condom during sex, then, while hiding the fact that you're about to cum, pull out, rip the condom off, and simutaneously slap her in the face with the condom while re-penetrating and cumming in the lucky girls vagina.
Last night I snakeskin slapped that bitch from the bar but I think she gave me herpes.
