I have significantly improved this question by doing the following:
Revised title and remove country / region specific slang (e.g: King hit in Australia)
Added the country tag of Australia based on the slang "King Hit"
Removed language not pertinent to the core question of the OP - speculating reason for the coworker assaulting the OP.
Clarified question of the OP to be work-place focused to avoid rant.
Could this community please vote to re-open this question? I would like to answer once it is re-opened, expanding on a good start by @ Glen Pierce.
