Hooking up

Is there a class that you have to go to to be on reality TV that teaches you to insert "hook up" in place of "have sex with"?

I was thinking about this the other day. I used to think that "hooking up" meant getting together with someone - usually in a dating-like persuation. But as I pay more and more attention, it's means to "have sex with".

Once I realized that - I realize the phrase is tossed around quite easily and frequently. Is this because they (people on TV) procreate more than the average human? Or is it because they've disguised what they're saying to where it's just too easy to say?

Hmmm?
