Touch Base 

To make contact; to cover all the possibilities. Comes from baseball where the runners need to touch the base to make a run legal. Mostly used by asshat salesmen and contractors when they want to talk to you over the phone to see if you're interested in something they have for sale, usually around dinner time.

"I'm just calling to Touch Base to see if you need our crappy product/service."
"No, fuck. Leave me alone."

frog baseball 

A reference to a very early Beavis and Butthead cartoon in which they treat the frog as a baseball, and hit it with a bat, just to watch it splat. Very funny.

Dude, that thing is toast, let's take it out back and play frog baseball

baseball wife 

n. like a gold digger, but this woman's specific intent was to land a pro-athlete. Often attempt "unplanned" pregnancies to land their victims/husbands. Found in large quantities in Paradise Valley and Scottsdale, Arizona, especially at Fashion Square Mall.

She's only screwing him because he got drafted by the team. She's so trying to be a baseball wife.

76th Base 

Oddly enough, 76th base is nothing more then a candle lit dinner in a cliched romantic destination. I know, what a let down.

Man 1: Dude, I heard you took your girlfriend to Paris.
Man 2: Yeah, we got to 76th base at an Italian restaurant by the Eiffel Tower.
Man 1: Oh well that's sweet... you fuck her after?
Man 2: No.
Man 1: Puss
