Scrapnel

Scrapnel is a newly coined hillbilly variation on the word shrapnel. Originally (mis)spoken by "Turtleman" on the show "Call of the Wildman" during the "Speedway Demons" episode when referring to a racecar crashing and throwing car parts around the track.

"If that car crashes, it may throw scrapnel around."

A grenade can explode, sending scrapnel into your face.
