ぶつける
ぶつける · butsukeru · JLPT N3 · verb-ichidan
to knock
💥 Sounds like boots-kick-ru: you knock something hard with your boots
Hear butsu as boots: a kick with heavy boots strikes hard. It is the transitive partner of ぶつかる (to bump into), so ぶつける means you hit something into something else, like bumping your head on a door.
