A himmie is a nice, cute, precious creature. Himmies are not the smartest one in the bunch, but they are hilarious and so funny to watch. You cannot NOT love a himmie.
From the German , a fart which is so loud that the lord in heaven can hear it.
Hans: ( farts loudly ) Ach du lieber!
Fritz: Zat was a himmel fart!
God: Cut the noise down there!
Fritz: See, God has heard your fart and isn't happy!
