deceptacon 

UK. A woman who appears attractive but is actually ugly. Can be found in a number of situations or for a variety of reasons. Clever use of make-up. Drunkenness in the eye of the beholder. Darkness in a club. Nice from afar but far from nice. If you've only seen a very well taken photo. Looks good but has an awful voice/mind/personality. Anything that might deceive you into thinking she's buff but she aint. Comes from Transformers - robots in disguise.

Be careful, I'd say there's about 85% chance she's a deceptacon.

deceptadong

A word used by Transformer nerds to describe a transvestite.

Steve: What the hell happened to you last night?
Bob: I hooked up with this hot chick and we went back to my place.
Steve: How did it go?
Bob: She turned out to be a man.
Steve: Really?
Bob: Yea. She was a deceptadong.

deceptacon 

Ever seen someone (a stranger) from behind and at a distance and thought, "Man, She/He is HOT!!!!" ?
Then suddenly have that person turn around around and realise that they are TOTALLY NOT????

That person is a "deceptacon".

Man, check out that hot chic over there. Hold on, OMG she's a total 'deceptacon'.
