The Grandma Grinder
The Grandma Grinder is when a man and his two brothers kidnap a girl’s grandma to lure her back to their place, waterboard her, slit her throat, and kill her grandma. The boys then cannibalise on both the girl and the grandma at an orgy/barbecue unbeknownst to the other attendees.
“Yo bro I don’t have plans this weekend want to pull The Grandma Grinder on Sally Hawkins?”
“Hell yeah dude!”
“Hell yeah dude!”
