What is a waifu? Well, if you're like me, you probably don't (or didn't) know what a waifu is. There are waifu body pillows, plushes, and even waifu simulators! To clarify, a waifu is an Anime character that someone considers to be their wife. It is usually used by male Anime fans. If you're a female Anime fan, you would use the term husbando, referring to an Anime character you consider to be your husband. They also have husbando body pillows, plushes, and simulators. The body pillow is usually just a pillow case, and it is called a dakimakura.
