In my defense... from SlangSite.com:

yummy: used to describe a person who's really damn hot.
Example: rachel leigh cook in antitrust for the people are inclined to liking girls and brat pitt in fightclub for the people who are inclined to liking boys.

So the question is... if not yummy then what?

---Derek Jeter? Well-formed.---

It just doesn't roll off the tongue as nicely as YUMMY.
