Giant enemy crab
From Encyclopedia Dramatica
In the past, one of the biggest threats to the Japanese way of life was that of Giant Enemy Crabs. The only way the samurai of old could defeat these terrors was by flipping them over with real time weapon change, then attacking their weak point for massive damage.
As the legend started on teh tubes lol was based on an awesome PS3 game called "Genji: Days of the Blade" or the US edition "GIANT ENEMY CRAB: PS3 FANBOY EDITION".
Ever since, happy Xbox and Wii fanboys have been repeating and imitating that phrase until it became a meme.
