This word was made by D.J. Butcher Utah (801)When you are smoking weed and chilling with your friends. We call it "shmellin" because you are smoking and chilling..
When you fuck someone in the ass and pull out, and your Johnson is greased in shit, and you tell her to suck it - but she says no, then you say, "It's only smellz" and put the Johnson in the mouth.
