Not sure if serious, but it's schlagen, but there's also greifen, to grip, if that doesn't sound intimidating enough, or schiessen, to shoot as in a gun or soccer ball.
But yeah, I'll try to limit Bryce's German to either him talking to himself, pronouns because his grasp of Japanese pronouns is roughly on par with mine, or when he's just too pissed to bother with Japanese, though I'll still put the helper text on the bottom of the post.
Also, if you decide to use schiessen, make sure you spell it s-c-h-i-e-s-s-e-n. If you flip the I and the E, you go from shooting to cursing
