no u

The end of all arguments in the whole world.
Used if your opponent doesn't have any arguments left to say.
For an example:

Dad: ur mom noob ahahah
Johnny: no u
*see your opponent die a slow, horrific death, that is full of blood and inner organs.
Please do not do this if kids or old people are close, as they will be traumatized
for the rest of their lifes.*
