Sexting, for example, is something only done by high school students. It is a "hey, I'm sitting around with no top on, why don't you run the 2 miles to my house and I'll sneak you in the back door so we can fuck."
"Hooking up" is nothing like he believes. People in relationships don't hook up. Hooking up is when you go to a party with a bunch of people, find someone who you dance with for a little while, make out, then head back to $place and sexile $roommate.
I don't even want to get into Greek life.
