A sexual act when a man "jimmies" his cum onto a woman's breats and then uses the cum as lube while he rubs his penis in between the cleft of her breats as she squeezes them tighter and tighter around his engourged member.
Kristen's boyfriend told her "I'm going to Jimmy Nip the shit out of you!" and she instantly got excited.
