the sound made when you try and piss with a boner, shooting towards the ceiling.
I woke up, went to the bathroom and shot a roif!
ROIF is an acronym and also a verb. It stands for, "Royal Order of Impacted Feces," and whenever mentioned should be accompanied by a hand gesture. The gesture is a closed fist with the index finger held up and curled so the fingertip points to 4 o'clock.
"Man, I am seriously ROIF today." Indicates constipation in the subject. Incomplete without the gesture. The gesture alone is used in mixed company. Never spoken in long form unless defining it.
