bluetick 

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."

BlueTicker 

Someone who keeps on reading messages, and yet does not reply. Their actions can be intentional, or they are just busy and cannot be bothered to reply. BlueTickers can cause much stress, especially when you text your crush and he/she just BlueTicks. BlueTickers can cause people to feel bad as they think they are being ignored. (The term 'BlueTick' comes from WhatsApp, when someone reads a message, the double-tick turns Blue.)

Alan: Why are you such a BlueTicker? You keep on reading my messages but you never reply. :(
Bob: I cannot be bothered to reply. :)

Blutack

Non-smelly, but very sticky, smurf poo. Has the tendency to get stuck between your toes and the bottom of your shoes. Not very tasty to eat but great for decorating!

Smurfette - "Oh..Yuck! Pappa Smurf...is this your Blutac on the floor? I almost stepped on it!"

Pappa Smurf - "Hmm...if it's round and blue then it possibly is my blutack....can you pass it to me dear?"
