Grundlefluff

When you fart, but the fart bubble moves up your inner-thigh instead of your ass, and pops when it reaches your balls.

Jim: Did you fart?
Michael: No, it came from my balls.
Jim: Oh, so it was a grundlefluff.

The Gesundheit

During sex when you throw black pepper into the woman's face and she sneezes, which causes her pussy to tighten on your dick.

Last night she was in the heat and we were on round three. I had a hard time finishing so I tried "The Gesundheit" and it gave me the bump I needed to get to the finish line.

Knickerflap Grundle Gravy

A thick, moist cream cheese like deposit, located primarily in the feminine crotch area- created by flap friction during vigorous exercise in high temp environments or in low temp environments depending on flap mass.

After an extended fast walk session, a large reservoir of Knickerflap Grundle Gravy was evident in the professional lady's yoga pants.
