Tumblizzard 

A group of people from Tumblr who band together to attack someone or something whether in real life or over the internet (not necessarily just on tumblr). The Tumblizzard acts as a hive mind with the queen (person who was first triggered) being able to control all of her loyal subjects.

Wow, did you see that guy get attacked by the Tumblizzard earlier?

Cumblizzard 

When a guy ejaculates into a fan, so the sperm flies all over the place, resembling a blizzard.

Dude, I was so bored last night, so I caused a Cumblizzard in my living room.
