This is a Japanese word meaning Explosion/Loud. It is also the nickname for the Character Katsuki Bakugou from an anime: Boku No Hero Academia (My Hero Academia). Bakugou's quirk is to let him make explosions from the sweat on his hands. His father's quirk is explosion - which is made from his sweat - is very weak as it has no fuel to power it. Bakugou's mother's quirk is glycerin which will be the fuel to Bakugou's quirk: Explosion. Bakugou is a very explosive person and is usually called this nickname by Deku (Izuku Midoriya)

“Kacchan!” Izuku Midoriya voiced breathlessly as he pleaded for mercy from the explosive boys grasp. Blood streaming down his face; he had tried to convince the boy that a fight wasn’t necesssry but that ultimately failed.
