(slang, chiefly Mid-Atlantic US) Something; a thing; any object, place, or person.
Jawn can mean anything—person, place, or thing. Sometimes if we’re telling a story and don’t want people to know what we’re talking about, we’ll plug jawn in for everything. The other day I was at the jawn around the corner with the young jawn from down the street. We get to the jawn, right, and the ngh at the door is all on his jawn, not knowing I had that jawn on me. Man, it was about to be on in that jawn.
