1) Term used to describe when someone is decapitated and another person penetrates the headless body via esophagus. This is similar to Skull Fucking
and is sometimes used in conjunction with it.
*Note: This is not a violent sex act as the victim could already be decapitated nor is it an inside joke. This term has been used numerously and in many places.
1) "My friend Ryan and I couldn't decide who would go first at the girl, so he Slash n' Smashed her while I Skull Fucked her."
