Polish Stoplight 

During intercourse, the penis continuously becomes dislodged from the vagina and thus causing a “stop and go” system in love making (much like a Pollack driving through a blinking red light). This is typically caused by a shorter than usual penile shaft.

Rebecca found herself in a Polish Stoplight with her husband because his birthday warranted their annual coitus.
