Basically its sperm. Its white, sticky and spreads like mayonnaise. But its the masculine term.
When you spunk all over a womans face you say to her, "how do you like that MAN-O-naise bitch"?....

Or, Last night my bitch ate all my manOnaise, it was the best blow I've ever received. My balls are deflated.

Or. Hey bitch want some manOnaise?

Do not ever put manOnnaise on you salad and this is plain sick!!!

Also know as bukkake but in a milder form. sperm,cum,man white, spunk
