the act of pissing in a condom either during or after having sex
My roommate John was so drunk that he pissed in the condom while his girlfriend was riding his cock, he pulled a dirty john on her
After having sex, pulling out, being too lazy to go to the bathroom, and peeing in the condom. Some say that this causes the condom to full up like a water balloon.
Because he was too lazy to go to the bathroom, he pulled a Dirty John in the condom.
the act of pulling out ones penis and slapping a teacher, or substitute teacher in the face... then tea-bagging them... named after john dove, at Alamogordo High
