Tronblr 

A group of roleplayers on Tumblr, with a surprisingly large fanbase, that extends into other fandoms.

Though Tronblr is known most for their slash and unapologetically self-aware crack they are also known for having rich and entertaining characterizations of those that they play.

Also there's crossdressing.

Tronblr just about exploded the other night. The Joker showed up.

Toonblr 

A community full of furries and robot fuckers. These Tumblr dorks completely deface the purpose of a children's game.

"I'm looking through the Toonblr tag and I found this porn of a furry and a robot. What the hell."

Troublr 

An alternative word for the website 'Tumblr' used by someone who thinks the site glorifies people with mental health conditions causing its more regular users to develop mental hypochondria purely for attention of others and followers to their accounts.

"Troublr has given every white teenage girl "anxiety", on and off "depression" and severe cases of ADHD."
