A suffix added to the end of a name of someone who is pompous, pretentious, and otherwise grossly beguiled by their own sense of entitlement, and their given name doesn’t justify their personality enough.
Lauren: I want to talk to your manager, I demand my 72 cents.
Ben: Chill out, it’s not a big deal. You’re being a real Lauren Amadeus Bandersnatch Weissenhaus right now.
One among many archaic nonsense words used in the classic poem "The Jabberwocky" by Lewis Carroll. Could possibly be a monster more horrible than the Jubjub bird.
"Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!"
The extrememly dangerous creature from the survival horror game Resident Evil Code Veronica X. Built to be the multi-purpose tyrant, they are equipped with a singular super strong stretchy arm. (hence the "band" as in bandy in the name bandersnatch) on there right side and have no arm on the left. Get too close they grab your head and crush your skull. Get too far away they will batter you about via stretching their arm. If you hide up/down stairs they will use the arm like a grappling hook to grab hold of an object and pursue. Very slow moving but deadly. Generally in packs of 3 but the occassional singular individual.
Best weapon for extermination: Bow gun with gun-powder tipped arrows. Golden Lugers. (as Steve shows in the game, saving Claire)
