bases

The generally used bases, as I've heard them in my region (SW PA):

1st Base - Frenching
2nd Base - Feeling and/or Hand Jobs and/or Fingering
3rd Base - Oral and/or Anal sex
Home run - Sex

Another version I've heard is the four Fs described in another definition, and also a kind of silly one that had sex at third, 2nd at anything other than sex, 1st at kissing, and home run as getting married.
Last night when my boyfriend was "up" to bat, we rounded _all_ the bases.

bases

You start out at home plate. Then, the ball is pitched to you, run to 1st base followed by 3rd base and then home plate again. Those are the bases.
guy1:"I was at first base. Then i was at second base. Then i was at third base. Then i was at home plate. So that means that i ran all of the bases."
guy2:"Wow! That's really informational!"
pervert:"Wow! That's really informational!"
