The act of being being extremely close to hooking up with / pulling someone but then stopping at the critical moment. You know you could have got the whole way if you wanted to but you thought better of it, often because you have a girlfriend/boyfriend. Essentially, your "ghost" pulled, but you remained faithful.
Man 1: I must have ghost-pulled about 3 girls last night, they all wanted me so bad.
Man 2: Thats good you remained faithful to your girlfriend, you are such a top bloke.
