Hazubendo

Ideally, if we weeaboo-fy the word "husband", like we have already done with waifu, this is what we should probably end up with. It is a term of endearment referring to a male character. But that is put aside in favor of husbando. A word that when attempted to be pronounced in the same way as waifu, will sound more similar to "Who's Bando?" rather than "Husband".
