14.
Noun. - A person who is in every single way, a pile of meat. More simply, an extremely ugly fat person. An ideal roast, more commonly known as a "roast head", would have a very wrinkley forehead with very saggy proportions, they would succumb to a terribly embarrasing squash shaped head with a chin that just never ceases to amaze you. A roast must also have the lazy personallity to go with it. Someone with starfish like qualities who doesn't accomplish anything in life. Its not a word you can completely understand with out seeing examples...
Very good celebrity examples of roasts or roastheads are the following...

Louie Anderson

Don vito
Ralph Kramden
John Goodman
