Replying to Booty Call? Good/Bad/Otherwise

I posted this in Ladies Men, but I'm inpatient

So there's this girl around campus. We've talked and chilled a couple times and I'm ALMOST certain she would be down for a friends with benefits/booty call situation.

So my question is, who here has had a situation like this and is it a good idea? I'm not looking for a girlfriend, just a fuck buddy. How has this worked out for others in the past? I also realize that it probably depends on the girl, but she doesn't seem (I can't be positive though) like the type to get it all twisted up with girlfriend shit.

Any tips/pointers? Thanks and +k to all advice.
