Fart-camouflage 

n. and v. The act of synchronizing coughing and/or flushing with an upcoming, potentially noisy fart in order to merge the sounds and avoid judgement from others when exiting. This usually happens in public restrooms or thin-walled houses; mostly done by females, although it is done by males when there is female within hearing range, fearing it might be a turn-off.

Girl 1: What the hell, Daisy flushed three times already.
Girl 2: Yeah, that's her fart-camouflage.
Girl 1: What a waste of water.

Dude 1: You ok man? Heard you coughing back there.
Dude 2: Yeah man, I was fart-camouflaging -- Daisy gets turned off by my farts.
