a lonely fatty, is some one who, in the school yard playground, has no friends, and eat waaay too much, also they listen to music that will burrrrrrrrrrn your eyes, such as, chris brown, and britney spears. they also can't get friends, girlfriends/boyfriends and are very unhygienic and have greasy hair.. they usually work at a fast food chain outlet, but spend most of their time there, in the storage closet, piggin' out on shakes and cheeseburgers.
liam:haha, that kid has no friends...
tom:yeah, he's a lonely fatty
liam:duhh, i saw him trying to tounge a cheeseburger the other day after gym class..
