Coramella

The little bump that you get near the top of pint glasses, to help prevent the glass from slipping out drunk people's hands.
"Hey, what do you think these bumps are called at the top of pint glasses? I mean, they must have a name? Something like 'Coramella' - from the Italian for bump."

"You should enter it into Urban Dictionary!"

"Haha, yeah."
