ka kaw ka kaw
When you're on a double date and you're too embarrassed to just go poop, so you yell 'ka kaw ka kaw' to tell the other person you're about to take a dump in front of them.
'Ka kaw ka kaw!' I yelled, and then I ran to the bathroom like my life was on the line.
He said 'ka kaw ka kaw' and then left the table like he was running from a monster.
She said 'ka kaw ka kaw' and then disappeared into the bathroom like it was her escape plan.
