An act in which a male (or any female with a strap on) participant uses one's penis to "punch" a hole through a solid product of defecation, effectively stimulating one sexually. Please note that the "chocolate bar" must be hard on the outside, but chewy on the inside, to be truly considered usable in the term "punching the chocolate bar."
guy1: hey, I just shoved my penis into a hardened turd.
guy2: Been punching a hole the chocolate bar , have you?
guy1: Can't help but be punching a hole in the chocolate bar.
