PSD

Otherwise known as "pyschosomatic diarrhea". It is brought on by eating an unsavory meal which is suspected to be made with a different type of meat than advertised by the restaurant. Your brain will automatically cause you to become ill rectally even though there is not likely anything wrong with the meal.

PSD

An acronym that stands for "Pees Sitting Down". This term refers to people with dicks that prefer to sit down when they urinate instead of standing. Standing while taking a piss is one of the great gifts of manhood, and relinquishing this right puts a man's masculinity in question. Used as both a noun or adjective, this term is reserved for guys who deserve the worst feminine insults.

Watching Bachelor in Paradise by yourself is a PSD maneuver, man.
