(Also DH) A person (male or female) that before going to a party or social gathering you are sure you can hook up with if all else fails. Basically, insurance. Because nobody likes to get left out a party right?
Mike: Hey Dave you going to Jessica's party?
Dave: Yeah man, as long as I have a designated hook up.
Mike: Oh yeah, Tina should be there, if things don't work out with anyone else.
Dave: I feel shallow for this though, Mike.
Mike: Don't Dave, we are humans and our need for love must be satisfied, just like our need for food or water.
Mike: I love you man.
