100000000th base

the act of doing a dangerous amount of meth and having oral sex with george bush sodomizing him with WMDs on top of 10 gay minorities in the middle of Times Square. Then you will proceed to jackoff on a gray squirrel and then fuck it nonstop for two days. Once you are done, you will wipe your dick on every nun's face and eventually it will get warts. When you get the warts proceed to suck your own dick repeatedly until you blow a hole through your head and fuck that hole cut off your balls throw them at your granparents and fuck them then fuck their little chihuahua and eat taco shit while fucking your own bleeding balls then explode an asshole in your mouth and you die. This is the most amazing feat you can possibly acheive. Congratulations

When asked by St. Peter what he has done in his life Bob says: Well, I dealt drugs, raped babies, and fucked my parents and sister on top of a pile of monkey shit, but I did get to 100000000th base last night.

St. Peter: Welcome to heaven champ.

365th base

The base attained after completing bases 1st-364th, one per day, starting on January 1st. You must reach home base with the partner of your choosing on top of the New Year's Day ball in New York City, and a climax must be attained at exactly 12:00 AM, when the ball hits the ground. This is the ultimate feat, and will make you more powerful then God and Chuck Norris combined.

Person 1: Dude, did you watch the New Year's eve show? I totally got to 365th base!
Person 2: Dude, thats awesome! What are you going to do now?
Person 1: Now i have to wait until leap year so that I can reach 366th base!
