look up any word, like wyd:
 
1.
When an extremely attractive female/male, is in a relationship with a very goofy or unattractive male/female. Commonly referred to as "out of one's league."

This word and definition combo was invented back in 2002. We were at Virginia Beach, hanging out. We noticed that all of the attractive females, were with very goofy/unattractive men. At this time, the men were carrying a pizza, which apparently helped them out. This definition has since evolved, as the lesser attractive of the two people now do not necessarily have a pizza with them.
Person A "How did Kim end up with Johnny? She is so hot, and look at him!"

Person B "Yep, that's goofundum at its finest!"
