Waifu pillow

Waifu (ワイフ - Japanese for "wife") pillows are the lulzy fictional wives of autistic basement dwellers with no lives. They feature a cute anime girl on it, usually printed as if to be laying down on a bed. If desperate enough, the basement dweller will begin to make an attempt at fucking the inanimate object, then inevitably fail.

Because the basement dweller is too autistic enough to admit when he's wrong about the waifu pillow not being an actual person, he'll ree at you if you dare make fun of his "lover".
