baduka
is a word used as a sound effect in a conversation to give a story life and make it more interesting to the listener or listeners. It is like putting the sound effect bam or bang or boom on steroids.
The first time I ever shot my grandpa's 10 gauge goose gun I almost shit my pants. I put it up to my shoulder and held it as tight as I could and squeezed the trigger real slow as I exhaled and BADUKA it went off donkey kicking me so damn hard I dropped the gun.
