nintenno 

Term referring to players of Digital Extremes Co-op shooter "Warframe" on Nintendo Platforms. This is a pun in 2 ways.

1) The player that controls a Warframe is called a Tenno; Warframes are considered Space Ninjas. Nin + Tenno
2) Nintenno looks like a mistype of Nintendo

... Puns are still terrible though.

The Nintenno are coming!

Nintendo Logic

When, in a Nintendo-published video game, the physics and design that work in the game are totally impossible or rather irregular in real life.

It's a bunch of Nintendo Logic that a boat that floats in lava will collapse if it hits a wall at low speed.
