Fifth Base

Most people will tell you that fifth base is butt sex. If you've lost your anal virginity, the below example is one nights equivalence to butt sex.

Wilson: "How are things going with Cuddy?
House: "Great, last night I got to fifth base. That's 2 home-runs and then she gives me back a triple."

Base Jump

To instantaneously extract yourself from a sub-optimal situation, often at great risk to your personal safety, professional reputation, or social standing

Original Use:
I just got called in to my partner's office to explain why the memo was late. All I wanted to do was to kick out a window and base jump the fuck outta there.

Modern Use:
Guy 1: I got caught in a conversation with Rufus again - that dude is so freakin' awkward.
Guy 2: I would have base jumped out of there by kicking him in the balls and running away.
