Captain Wankstash

A name first used in spoken conversation when referring to the fictional character Simon from the TV series The Walking Dead, who supported an excessively flamboyant moustache and cheesy grin. This, coupled with his attempts to emulate his boss Negan and general wankerism led to the formation of the moniker.
Similar examples would be: Douchie McDouchebag; Sergeant Dickface; Lord Twat of Knobington Manor, etc, of which the original creator of the name Captain Wankstash seemingly has an endless supply.

Can also be written Captain Wankstache

Suggested use: for mustachioed military/ uniformed non-military types, with attitudes far in excess of their competence /accomplishment. Is not restricted to this use but it's a good fit for it.
