perfect 10
A person who is absolutely perfect on a scale of attractiveness, from 1 to 10. Most people agree that there is no such thing as a perfect 10, and that ratings usually only go up to about 9.7 or so.
Example:
Randy: Dude, Megan Fox is totally a perfect 10!
Willy: Nah man, she may be the hottest ever, but she is still only a 9.5.
