Husbando is the word for husband (obviously) in the weeaboo language.
A weeaboo is any person that is not of Japanese ethnicity, that is obsessed with Japanese culture, such as anime and manga, Japanese language etc.
It is the word husband so-called “weeaboo-fied”, similar to how the English word “wife” became weeaboo word “waifu”.
A Husbando is referred to as an attractive, fictive male character in an anime, manga or video game that is considered husband material.
It is pronounced something along the lines of “whose-band-oh”.
The word was made up by weeaboos, Japanese culture fanatics, that don’t necessary actually understand Japanese language, but want to “Japanize” English words to feel more part of the culture.
“Waifu”, the weeaboo word for “wife” came first, but seeing the need for a male version, Husbando soon followed up.
The term is mainly used by Japanese culture fanatics – weeaboos – when referring to attractive male anime/manga characters.
