(n) Anyone who is obsessed with the television show Glee may call themselves a "Gleek". It is a combination of the words "glee" and "geek," implying that the person is a "Glee Geek." This is similar to calling someone a "Trekkie" (someone who is obsessed with Star Trek) or a "RENThead" (someone who is obsessed with the musical RENT).

Bob: Of course I did! I'm such a Gleek.
