Having sex to the point where you are so sore you can't move, then forcing yourself on top of your partner and bouncing up and down.
1st guy: "Dude I got to 50th base last night"
2nd guy: "I thought I heard you two screaming, but I had no idea."
1st guy: "Yeah I can't feel my junk now."

highly debated base when talking about sexual accomplishments, all that needs to be done is to clarify what "league" youre "playing" in.
second base in minor league baseball is feeling a girl up.
second base in *major* league baseball is fingering or handjob.
Major league- 1st base makeout with feeling up; 2nd handjob/fingering; 3rd blowjob/ eating out; home sex
minors- 1st base makeout; 2nd feeling up (breasts); 3rd oral/fingering/handjob; home sex

Having sex with Buddha's belly button, and becoming the new Buddha. You then go through a series of events very much like the Santa Clause Movies.

When you fuck everyone you know who possesses a name beginning with the next 5 letters in the alphabet after yours. You must then do 69 + 5 other positions to equal 74
Person A:- Guess what, I reached 74th Base with Rob last night
Person B:- I know, because I was the letter U
Person B:- I know, because I was the letter U
