ninja shitting

While at work or at the house of someone new you are dating, sometimes you don't want to have a loud shit. So, it is neccessary to be stealth like clenching your ass cheeks together to eliminate trumpet-like farts or take your dump very slowly so as to minimize the sounds of fecies hitting the water.

Phil: the walls are so thin at work I'm always ninja shitting.
Sarah: Yeah, I totally understand.
