Radishes:

Sliced thin, covered with vinegar, salt and pepper.

Here's a definition of 'radish' from urbandictionary.com with one of the words censored by me to protect the innocent:

Term usually used in Panama City Beach, Florida, at Spring Break, meaning "really awfully drunk in a shi**y hotel." This term was coined by a large group of spring breakers from south Alabama and the "Radish phenomenon" has begun to spread rapidly.
