It's when you're doing a chick from behind and before you break off, you spit on her back (thereby 'deceiving' her into you thinking you are done) and then when she turns over, you blast her in the face.

The feeling you feel of reality after watching the movie: Inception.

When crap definition's get published and decent one's do not.

When you get your ass kicked when you are expecting something and it turns out to be the shittiest thing ever.

what you get by watching Christopher Nolan’s Inception.

A deceptive fart would be when you are about to fart, and just before the fart leaves your asscheeks, you realize it is in fact Shit. Therefore resulting in you having to clench said bumhole and try to suck the poo up. Can result in failure, where you shit yourself, or excruciating pain.
