Jelly Nipple
A womans nipple that does not become erect during arousal.
Bro I was with this girl last night and I said damn whats up with the jelly nipples.
Nipple Jelly
A toxic substance formed over time by a series of steps in which food substances fall into crevaces of fat below the breasts, and are broken down by the sweat of the fat person and become fossilized like amber, and when methane gas builds up the crevace are blown open and the nipple jelly emerges.
I bumped into a fat person's breasts and his nipple jelly burnt off my arm. He tried to apologize while the toxic substance burnt through every nerve in my appendage.
