derived from the latinish phrase-word thing caught-red-handed. its when you know your dad isn't home and you hear whoreish, moaning noises from your parents bedroom and you walk in and you see your friend fucking your mother in her vagina and then at his climax pulls it out and sprays his cum all over your mothers face and other body parts such as her hands. he then will take his penis and stick it in your mothers mouth causing his wiener cheese to spray all over your mother. best when done with people named Susan. also known as friend-cum-in-your-mothers handididation.
