The direct oral deposit of a formidable, fiber-enhanced sequoia of fecal matter into your lover's gaping maw.
Originally an
underground slang term, circa approx. 1994. Orginated amongst a small circle of future computer geeks as they crowded around a 14" monitor, with 28.8 modem blazing along at what was then considered ludacris speeds. They waited restlessly for the image of what they hoped would be a nice all-female orgy to appear, but were repulsed (and later intrigued) to see a woman lying naked
on the floor with her mouth open as her male partner stood over her and crapped in her mouth. The image filename, originally a few
random letters followed by some numbers, was re-named "SMELLSNACK.jpg" and happily distributed via email to brighten everyone's day.
