An old-school system of telling people how far you've gone. While there are different versions this is how it

1st base- French kissing
2nd base- Feeling up, boob touching
2nd and a half base- Fingering, hand job
3rd base- Any form of oral
4th- Sex. All the way.

Can be summed up as french, feel, suck, fuck
According to the Base System, he figured that he had never hit more than 5 singles in his life.

Amy: "How far did you and Bob get last night?"
Lauren: "We only got to second. He just won't let me in his pants!"
