In tennis, someone who is no
good at all, or who thinks they are
good and really aren't. Origin is from "minute steak," 30 seconds on one side, 30 on the other, to denote
winning two easy sets from them.
Origins are in WNY in the early 1990s, popularized by B. Ziemba. (1969- )
Can be popularly used to mean anyone who sucks at a given skill, not only just tennis.
Steaks get "torn off" when they get beaten, as they are always apt to be.
