up can be anything from kissing to intercourse. It's deliberately
vague and undefined by this generation so that when you tell a friend
you hooked up with someone, you’re really not saying anything
at all. It’s a lot easier to say “I hooked up with someone
last night,” than to say, “I gave Johnny a blow job.”
It conceals what you’ve done, and you can talk yourself into
thinking it really doesn’t matter.
