Tumble Twat 

A Tumblr user that gets offended at anything and everything you say.

George: You're gorgeous!

Alexandra: You fucking fuck boy! Why do you have to oppress women?

George: No need to be a tumble twat.

Tumbletwit 

A devilish insult that causes great harm to the poor soul unfortunate enough to be so violently attacked. Be careful when considering such a word.
Like Nitwit, but worse.

Paul told Steven “Learn how to drive tumbletwit”
Steven had to pull over as he was so painfully hurt
