people for whatever reason, consider m80's to be "fireworks" or "firecrackers". but dynomite is an explosive, and whats an m80? quarter stick of dynomite!!

they don't make big colorful sparks in the sky, nor small colorful sparks on the ground/partially in the air. no,the soul purpose is to literally blow something up with an m80. a solid object, not just blown of for the hell of it. make sense? stupid? idk. idc. it's just my point.
m80. there's the freaking example.
