I'm gonna break your nico nico kneecaps

What a weeb or otaku says when he's going to lay you out on the floor and he means it.

If I catch you trying to steal one of my anime figurines again, I'm gonna break your nico nico kneecaps.

That's a line most weebs use, usually meaning that you should probably step back because this is a person looking for a fight.
