Hall of Fame Thirdbasewoman 

A female that is extremely adept at giving fellatio, sucking dick, polishing cocks etc.

Dervied from the notion of oral sex being third base, and there in the enshrinement into the Hall of Fame for exceptional play at the position.

Cory : Wow, what a first date, Michelle was fucking Mike Schmidt on my cock last night. She's fucking George Brett with a dick in her mouth. Couple more like that and I'll have to enshrine her as a Hall of Fame Thirdbasewoman.

Allison : She ain't shit, unzip your pants and I'll take you down like Brooks Robinson.

Cory : Please, last time you blew me it was like Scott Brosius meets Jerry Hairston Jr.

Allison : Ouch.

born on third base 

term coined by the great Barry Switzer to describe someone who was born with a silver spoon in their mouth but has an arrogance and thinks their standing in life is because of their own doing.

The Cooker: "i hate hanging out at the Kirk Hotel with all of these arrogant, rich punks that think they are an international man of leisure."
Pete Dick (calling Oak the goon): "look dude, just focus on jacking for beats and I will take care of these fucks that were born on third base."

A: Did you talk during it?
B: Yea, it was pretty weird...
