third base

Controversially debated, but the modern accepted definition of 'Third Base' is both Fellatio and Cunnilingus.

Fellatio being oral sex performed on a male, involves a penis being placed into ones mouth, commonly known as a headjob, sucking off or a blowjob, although one generally does not blow when performing.

Cunnilingus being oral sex performed on a female, involves a tongue entering a vagina, commonly known as licking out and eating out.
Late Tuesday night, Mike drove Jen to make out point in his newly imported supra, once there Mike managed to reach third base for the first time with Jen when Mike licked Jen's vagina. Jen had never given anyone a blowjob before and decided she would perform one on Mike the same night. That night Mike and Jen reached 3rd base both ways.

second base

1) The second of four bases (including home plate) in the game of baseball.
2) Many argue the status of this base in terms of sexual engagement. Some believe it is intense feeling, while others believe it is a handjob/ fingering. Take your pick.
1) Johnson reached second after pounding a double up the middle. He gave a two finger salute to the crowd, acknowledging his 300th hit.
2) Johnson reached second with his two finger salute pounding up the middle.

2nd Base

titts, dick, goods, anything you wouldn't try to cover up from your spouse/partner. Alan is two basses from doing his girlfriend, he's already touched her breasts, so he's past 2nd base.

48th base

(noun) An achievement that requires you to do the following... Go into a time machine, on Wednesday, in order to change the history of your life, thus causing a paradox. Once the paradox is set and parallel universes are being spontaneously spewed into existence, you must find one with a real life Jurassic Park and shoot all the protagonists dead. Take their bodies into a large volcano as a sacrifice to summon Mr. Pamplemousse, the fire god. You will them perform 23 bases of your choosing on him, whilst whistling the Star Spangled Banner, Old McDonald, and Dragostea Din Tei. Finally, you must have already done half the steps while raping 89 squirrels along the way BEFORE you read these instructions!!! All this must have additionally been done without ever losing The Game.
Person A: "After my lifelong quest, I have finally done it!"

Person B: "Done what?"

Person A: "I've reached 48th Base!"

Person B: "You made a paradox, destroyed the plot of a movie, and went squirrel crazy without being instructed to OR losing The Game?!"

Person A: "Yep!"

Person B: "Really?! 89 squirrels!?"

Person A: "DAMMIT, no!!! I did 90!"

Person B: "Better luck next time."
