Beats is a slang insult towards fat people. To be "Beats" is to be obscenely fat or overweight in such a way that you are repulsive and have no chance of getting laid. To be used effectively the word must be screamed in the face of the fattie. After you use the word you must deny all knowledge of how you came about the word and what it means.
