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."

Fifth Base

The true test of a relationship. It is when a male and a female truly love each other--through marriage, pregnancy, children and everlasting happiness. Sure, it may be cool and stuff to go for the milk instead of buying the cow, but you won't be saying that when your temporary slutty partner begins to hate you.
Lifeless dumbass who is too insecure to use a spoon or watch the movie Titanic: Awww man. All that work I did to get to a home run and now I have to start over. I envy all the nice guys and girls actually able to sustain a relationship :(
