Popular nickname for a commercially manufactured (prior to 1966) civilian version of the military M-80 firecracker or 'Simulator, Artillery, M80' and more commonly known as a Silver Salute. These now illegal firecrackers were slightly smaller in diameter (1/2" vs. 9/16") than the M-80 but of equal length (1-1/2"). They were silver in color, side-fused, and typically sporting a green colored safety fuse (visco fuse) with the words "DO NOT HOLD IN HAND" printed spirally around the outside of the casing.
Ash can or Silver Salute. Silver colored, 1-1/2 long, side fused, American firecracker.
The old form of the word trash can.
