The best fuel for potato guns.

When you're fucking a girl and about to finish, you pull out. While finishing yourself off, you put your finger most of the way over your tip so that you spew like when you put a thumb over the end of a hose. You must spray jizz all over the girl's hair, then scrunch it all up so it looks like Jersey hair.
Named after the infamous hair spray used by so many Jersey girls before going out or to Bon Jovi concerts.
