In all seriousness, I never learned what is meant by getting to first base, second base, third base and home.
I am talking of course about steps in courting behavior.
Could someone provide an answer?
First: kissing
Second: fondling through clothes
Third: touching/licking uncovered “naughty bits”
Home: SEX! 
And for some more input on the question:
What is your interpretation of the bases?
Is “third base” heavy petting or dry humping?
–sublight.
It looks like the reason I didn’t know what the four bases were is that there is no consensus.
According to some otherwise forgettable comic, possibly Bill Mahr…
“We have a constitutional crisis because Bill Clinton and Ken Starr disagreed on the difference between 3rd base and home.”
