A act of humorous resistance. The thing you do to the helmets of cops dressed up in riot gear with an empty water cooler to protect yourself from their completely unnecessary violent force against your peaceful university pro-Palestine demonstration.
That well-informed college student on the right side of historyjust “bonked” that police officer on the head with an empty water cooler! Legend.
When you use the largest blunt object possible. Oversized swords are not bonk. Comically large hammers and clubs? THAT'S BONK. In Elden Ring, Bonk players use something like a club or giant club. Anyone can use magic or a sword, but not everyone can embrace the bonk.
