The onomatopoeia for a phlegmy cough

Mik was in the hippie health section of the grocery store yesterday and came across this Head Scratcher, Umcka. I believe "umcka" is the sound one makes when trying to clear phlegm from their throat, making this irritating name an onomatopoeia, or what is also called imitative harmony (or in this case, an irritative

harmony). An onomatopoeia is a word that imitates the sound it is describing, such as noises like "oink," "meow," and in this case, "umcka."

Umcka is "new to the US," from Germany, the same country that brought us "Obama Fingers" and Wienerschnitzel.
