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!!!

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.
