Soft Waffle

When a man who is very intoxicated (often off of large quantities of Whiskey) attempts to have intercourse with a woman in the doggy-style position, but finding that his penis is too flaccid for penetration, just ends up undulating the limp penis in-between the woman's butt checks.

"After buying him 3 or 4 Fire Ball shots, all I got was a soft waffle."

"Nothing ruins a good night like a soft waffle-ing."

"At first I thought he was really hot, but he just turned out to be a no good Soft Waffler."
