Dunkin' Yonuts occurs when a man inadvertently causes the latrine to overflow during a "courtesy flush," thereby coating his teabag with a layer of shitwater.
"Dude i took a dump and flushed and the toilet overflowed but I didnt realise it until my balls were completely submerged in shitty water. What would you call something like that?"
