An unfucker is some one who is a smooth playboy, and totally convinces you that you do want to have sex with him, but when it comes down to it cant hold up his end of the deal for one of the following reasons:

A. Drank too much and cant get it up.

B. Is terrified of having sex perhaps for medical reasons (ie, fear of premature ejaculation or has had some type of accident or surgery)

C. Has some type of STD like herpes that he is scared he would pass on to you.

Sometimes it gets really awkward when you encounter one of these unfuckers on a one night stand, waiting and waiting for the punchline... but it never comes.
Jacie: OMG, I cant believe it, all that smooth talkin and Marcus turned out to be an unfucker.

Tina: What? He unfucked you too?? Gosh, that guy totally unfucked me, and I was sure I was getting laid. I think he is unfucking that little Turkish girl now. Poor thing, soon she will find out hes an unfucker too.

Something that is so amazing, so perfect, so awesome that you just can't FUCK with it. Nothing in the world beats it, it's the best of its class.(i.e. Unfuckable)
Ex:
man my car is fuckin amazing, it's mid-engined, rear wheel drive, lightweight, has just the right amount of HP to enjoy the sportiness while being very efficient as a daily driver, and of all else is fucking HOT. Not only have i found the best car in terms of performance but the best car in terms of appearances as well. The Toyota MR2 is UNFUCKABLE.

Ex2: yo man that routine i ran on that girl was UNFUCKABLE, it works every time.

Ex3: i pimped that bitch like no otha...unfuckable!
