n. Affectionate slang for an unborn baby. We've used it in our family for a while - it's a distortion of the German word "merckle" which means "little creature". My family tend to mash words horribly, hence Merckle became Mookler! We also shorten to "Mook", although I know that's a Brooklyn wise-guy!
