look up any word, like cleveland steamer:
 
2.
Fishing out the log you just dropped from the toilet. Find the nearest person and throw the shit like a 90 MPH fastball. It's only a strike if you hit the persons mouth.
I got so tired of this bitch running her mouth. I had to shut it so I decided to give her a Oral Hershiser. STRIKE!!!

When a person inserts a baseball into a man's rectum, then performs fellatio on the man whilst he clinches on the baseball.
Piazza's rectum looks like a Babe Ruth era catcher's mitt these days! Must be all those Oral Hershisers that Keith Hernandez gave him.

3.
When a female is giving you dome and somehow blows out her elbow like a major league pitcher.

4.
The act of being fellated by a woman while standing (she's on her knees), cumming in her mouth, and pulling a quick 180 to then fire out a log into her cum-filled orifice.
Event form:
I'd been eating fiber bars all day to prepare for our Oral Hershiser.

Verb form:
She gave me oral, then I spun around and hershised that bitch.

5.
The act of a girl (or guy, for all of you Lance Bass-type people) fellating a guy, and then having the guy defecating in the girl's mouth. This is not to be confused with Orel Hershiser, a former MLB pitcher and current analyst for ESPN.

Man, Sylvanta wanted me to just orgasm in her mouth, but I gave the Oral Hershiser instead.
