Ninja Tank 

In RPGs and some MMORPgs, is another word for a character that can be in the forefront of the battle and survive the outcome due to sheer evasiveness rather than high armor and health. An example would be the assassin from the pseudo-MMORPG game "Guild Wars", especially in PvP mode.

"OMG, why duz teh PVP 'Sin not die? teh whole team is attacking him... I h8 ninja tanks

Singing ninja tank 

A character from let's play of Cocoron by Deceasedcrab. Term suggested by a fan through a music video about a singing ninja tank, that Deceasedcrab dutifully voiced.

Let's go singing ninja tank
Ninja tank, ninja tank,
Sneaky singing ninja tank,
Ninja tank, ninja tank,
Defeats his foes with a song
As his treads keep rolling along!
