First, ignore his friend request. Second, if you are out for meaningless interactions. Only give others meaningless information. Either he knew you beforehand or he found out to much about you during a drunken romp. Either way you threw a friendship or at least an acquaintance away or you give away to much information to achieve your goals.
Reject him with a nice comment like dude your a good fuck but it was a one time thing.
Even if he was shit you made him feel good.
I had to do it with girls
He probably just wants to keep you on the back burner as a fuck. If you don't want to have any contact with him, then don't accept it. There's nothing wrong with that. The hookup was what it was so you have no obligations to him.
If you don't want to add him, then don't add him. You shouldn't be worried about what he thinks. You decide who you want to add on Facebook, heck I even rejected a request from a family member...
Don't add him then. Why do you care what he thinks? You already said it was just a guy you banged. He lacks good judgement by sending a request, but you don't have to

If you admit that you don't a round 2 with him then don't add him, because this is what he wants for sure.
Just ignore the friend request.
Ta da.
