“Gumma banthu Gumma….” in those good old days when we had little knowledge about darkness, Mom and few other elders used to use this line to scare us for all good reasons though 
. To make us not to go out of house at night, to make us eat our food etc. I’m not scared of them any more though.
I found this line logged at IRC yesterday, while I was busy at work . hmm… Gumma. (Ghost).
