Asstakash 

Noun - a particularly healthy looking female deriere.

In the 1984 classic Revenge of the Nerds, Toshiro Takashi wakes up to find that fellow nerd and frat brother Louis Skolnick has spent the entire night looking at the loving coed Betty Childs via the spy cameras the nerds installed in the sorority house. When he questioned him, Louis replied something like: "How can you get tired of looking at that ass, Takash?". "Asstakash" is a combination of "ass" and "Takashi".

Example:
"Have you seen Ashley in those hot pants? Man, what a nice asstakash!"
