Speed Gap 

The small, triangular air space located at the junction of a woman's thighs and pelvis. Speed gap is typically exhibited by voluptuous women and is not to be confused with the gap exhibited by slender or emaciated women.

Yo dawg, did you see Brad's mom's speed gap? I want to give that milf some atm action!

Yeah dawg, that slut's built for comfort. Somebody better be tappin' that ass.
