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.

grundel gravy

The sweat that accumulates in the resevoir that is the spot between the penis (or vagina) and asshole. Usually smells worse than other forms of sweat and is probably toxic.
