whilst enjoying one of what you believe to your own farts, someone else will apologise for it being from their anus. Thus leaving you feeling filthy and violated for enjoying the smell from someone elses guff box.....
imagine sitting, watching the tv, full of self admiration for having bowels capable of developing and delivering a smell so hideous to others but fragrant to yourself when you nan fess's up to having split her cholostomy bag. - fart raped
Sneaking in a silent and pungent fart, not warning the intended victim. Different than an SBD (silent but deadly) based on torturous intent.
My girl friend totally fart raped me while we were hiking. When I started gagging she just laughed.
