YT Watchdog

YT Watchdog is a guy on YouTube, who wears a dog mask, and a blue janitor's suit.
He says how he feels about all the haters and lamers on YouTube, and things going on in the world.
He is fucking HILARIOUS!
He talks really slow, then speeds it up, so his voice is high pitched..
He's amazing, and I love him :)

Hairy lady watchdog

Usually a quirky twitter woman/furry that doesn't like it when men make fun of some other quirky twitter woman's/furry's unibrow and overgrown armpit hair they show off on Tik Tok/Twitter to defeat the patriarchy.

Normal human being: I'm really not into hairy girls but you keep up being pressed about it.
HLW: Well she don't want you either!
Normal human being: Whatever you say, hairy lady watchdog.
