Similar to an Alabama Hot Pocket, a Harrisburg Hot Pocket involves a man (or woman with strap-on) to poop into a woman's vagina WHILE she is currently on her period -- then they proceed to have vaginal intercourse.
Situational:
Lisa: "I got my period today and I'm horny..."
Chris: "I just took a Viagra and ate 50 wings, time for a Harrisburg Hot Pocket!"

Conversational:
"I can't wait until Amy is on the rag so I can give her a Harrisburg Hot Pocket."
"Rich follows women around at the store who are buying tampons to ask if they want a Harrisburg Hot Pocket, he's such a sicko!"
