at times even vaccums boast of reverse engineering

i wonder if anyone has thought of a world where instead of scrapping or gunfighting or sword fighting or even pillow fighting, everyone had a pocket full of grenades and when they wanted to start some ruckus they just found that person, took the pin out and threw it at them. We would all have grenade battles and people world riot. This would lead to piles of innocent casualties such as piles of kittens and piles of hateful imaginary feuds between practicioners of hyper evolved cultural racisms. Maybe instead we could manufacture and distribute mystery grenades containing various styles of soup or pheromones or absurd amounts of glitter. If I got hit by a glitter grenade I would be both upset yet motivated to retaliate with an ugly grenade such that an immense ugly explosion would multiply the ugliness of said target by twelve. I don't know why but recently and naturally this comes to thought every other day.
