Slang term for someone who is "verified" on Twitter, derived from the blue bubble with a tick in it that appears next to their name. Usually used in a derisive sense, particularly with reference to journalists, as "bluetick" journalists will often exist in the same small network and therefore become susceptible to groupthink.
"Some bluetick QTed me the other day to tell me my opinions were bad, my mentions were a mess for a week."
An extraordinarily small means of measuring length. Never fully determined how small because it's never actually been found and measured due to the thick jungle within which the original Bauerdick is located. However it has been estimated that a single Bauerdick Unit (BDU) may be close to .000001mm or 1mm * 10E5.
"Wow, that ant must be at least a thousand Bauerdick Units (BDUs) long!"
