Kakella
When you're so full of poop you feel like you're about to explode and you just have to say it out loud.
'Kakella!' I said as I sat down because my pants were about to rip.
My friend said 'Kakella!' during the movie because the popcorn wasn't enough for her.
My grandma said 'Kakella!' while making breakfast because she had been holding it in all night.
