waifu means the carton/movie character (in this case daisy the donkey) is the imaginary wife/husband of some one. so basically the person in question(gumball) has a relationship with a person/creature that in reality is not real, but the person will treat their waifu like a normal girlfriend and will not cheat on "her/him"
any way this pic made me laugh. keep up the good work!
Nice work as usual!
