After performing ATM on someone, during which you've pulled out a plum, their teeth become fouled with said plum they become angry and sad and in a horrific grimace have a shocking resemblance to a jack-o-lantern.
My third grumpy pumpkin was with Angela. That bitch was already missing a tooth so it didn't take much to go full pumpkin.
