Nerf This! 

A line that the character D.Va says in overwatch when she uses her ultimate and causes everybody to run for cover. D.Va's ultimate is self destruct and everybody in a certain radius gets dealt a HUGE amount of damage.

D.Va: Nerf this! {self and opponents}
Opponents: OH SHIT RUN FOR FUCKING COVER!!

*playing overwatch* Nerf This!

Nerf This 

In the game Overwatch when D.va uses her ultimate ability.

I was stuck in Zarya's ultimate and I heard "Nerf this" and I was suddenly dead.
