Although synonymous with "unbeatable", it can be used metaphorically to refer to anything you hold in high esteem.

Derived from the game of chess; checkmate is an offensive position in which the loser cannot move his/her king out of "check" (ie: imminent defeat).

Checkmate therefore means "unbeatable" with the implication that it is highly desireable to obtain.
"Hey man, have you heard that new Red Hot Daggers album? It's fuckin checkmate!!!"

To sit next to someone in a bathroom stall and then have a really stinky crap. As with chess, this puts them in a position where they are under direct attack, that cannot be avoided.
“I sat in the stall next to Bob and had a big smelly crap. “Checkmate Bob, checkmate.”

Checkmate (pronounced Shek-ah-mah-tay) means whatever you happen to think it means, it is the greatest word in the world.
Man, I really want to checkmate that girl.

That hat is absolutely checkmate.

We went to the checkmate and had a great day.
