Originated from the Greek word Mandimandioti.
v. To give someone a Mandis is to put a woman in a wheelbarrow, cover her with dirt and then fuck her.
*Please note that this does not work with guys because guys don't have fucking pussies!
Man 1: "What's wrong with your sister? She looks all dirty."
Man 2: "Oh that dude Mandissed her."
Man 1: "That's horrible!"
