Man-naize 

When your man juices congeal to a custardy substance and it gits all thick like mayonnaise.

Yo, J'nielle! Dat dime was so poppin last nite dat I couldn't even make it. My man-naize got all over her belly.

man-o-naise 

A slang word for semen, playing off of seminal fluid looking white and pasty, like mayonaise.

That "ho" just swallowed all my man-o-naise.
