A combination of "Sir" and the ending letter "T" which is short for faggot. Can also stand for any other term meaning someone is a loser or lame.

Get the Sirt mug.
1) a combination of sir and faggot which sounds similar to what is expected so it goes unnoticed.
2) when you are forced to call a douche bag "Sir" to play the "game".

3) A person who demands respect but has earned none of it.
As I was walking down the hall, I saw the VP of Nothingness and said "Hello, Sirt" in a loud confident manner as this is what he wants. I was thinking to myself that this dude is the biggest douche bag in the history of the vagina which allowed me to have an honest smile while I said hello.
