Mindlessly macho

The kind of person (not always male) that does things like hit themself in the head with a beer can until it flattens, or with a beer bottle to feel something. They might identify as a jock or as a machine, but the difference between them and other people that have also played sports is they don't know how to turn their own switch off, they are too busy trying to flip somebody else's switch on and off all the time.

He/she was mindlessly macho, always trying to outmacho or outtough the next guy.
