A person named Steve whose lack of interest in women makes him look sterile. Commonly known as "The Sterile". Never try to unsterile The Sterile, that just leads to misconceptions and awkward looks from his roommate. He also thinks he can play the guitar really well and he thinks his voice is like heaven and posts videos of him doing that on YouTube. These videos if seen could prevent him from ever getting a job anywhere because they are so horrendous.
-His name does not have to be Steve to because a Sterile Steve-
Character in Strong Bad's "Sweet Cuppin' Cakes" concept who is not exactly a person. Looks like a brown block with eyes and a mouth. Shows up once an episode to deliver his catchphrase - "Eh! Steve!" Sworn enemy of the talking wheelchair.
