For M-80 we have a term and definition in Pyrotechnics.

A small, powerful explosive created by the military (supposedly that's what the M is for) for use as a grenade/gunfire simulator, and later sold as a large firecracker. Once very popular in the U.S., but was banned by the CPSC as part of the Child Protection Act in 1966 due to the thousands of serious injuries they caused. Often classified as a "firework", especially by the anti-fireworks media, even though it is NOT a firework.
