look up any word, like dirty sanchez:
A Maso-kisser can also be described as a face-muncher or lip-gobbler.
This is a phrase levied at a person who adopts the technique of French kissing which involves (often as a result of drunkenness) a wide open mouth and sloppy salivarius gobbling action known as a maso-kiss.

The action is both unpleasant, forceful and can be painful leading to the expressions connection to masochism.
That filthy ho was a serious maso-kisser.. she practically ate my face right off!!
