"shut up, douche nozzle!" or "Greg, stop being a douche nozzle."
A mythical three headed beast that exists within a workplace (usually an office) whose sole purpose for being is to verbally abuse and harass their manager, who try as he / she might, can never seem to do enough to stop them from breaking his spirit, day after day after (long and weary) day
On their own, any one of the three parts of a douche nozzle maketh an easily defeatable foe, but when combined (like Voltron), they form a truly unstoppable workplace bully
A person who you don't really want to talk with or be around, but for whatever reason, you end up needing to.
"The only way I get to go to that party is if I 'm that Douche Nozzle's date!"
