The word "cheeks" or the phrase "that's cheeks" is used to describe something that is really bad. It is a version of saying "that's ass", as instead of saying that, one could say the phrase "that's ass cheeks" and shorten it to either "cheeks" or "that's cheeks". This is typically used in New York or the Northeast U.S.

A man so irresistible and tasteful that beings of all sexual orientations desire to be his life partner. A man who falls the subject of an infamous chant at football games, and supplied Ryan deburger with his sloppy seconds.
