The sexual act in which the male bangs the female in the doggie-style position and upon ejactulation, releases his semen between her butt cheeks and mashes them together, thus creating a medley resembling that of a mayonnaise sandwich.

A food enjoyed in the ghettos of the Dirty South while growing up. It is made by spreading mayonnaise on one slice of white bread and then covering that slice with another. Often accompanied by some sugar water to wash it down.

When one jizz' on a pillow and flips it to squish the jizz covered pillow on a bed like a mayonnaise sandwich.
Chris pissed me off so I fucked my girlfriend in his bed and laid a nice mayonnaise sandwich right on it.
