nacho bowl
If a woman is to have sex with more than one man, when a guy leaves his cum all over a girl's pussy for the next guy, so when guy 2 goes in it sticks all over his dick, like tortilla chips in nacho cheese.
"Her husband was pulling into the drive-way, so I nacho bowled his wife, and left the fucker a mess."
