When you've eaten too much and keep eating, then you get #nellybelly. Everyone will notice your Nelly Belly because it does not look like a normal belly. It looks like Nelly Belly. You look a bit like you're getting pregnant. Both men and women can get Nelly Belly.
"OOO Nelly stop eating dude! You're getting NELLY BELLY again."
"Oh no, I got NELLY BELLY, I feel bloated, think I am gonna explode."
