ka-bunk-a-bunk
A butt that’s not fancy but it’s big and it’s making you scream in the middle of the street.
That ka-bunk-a-bunk made me scream in the middle of the street.
I saw that ka-bunk-a-bunk and I had to yell, ‘what the hell is that?’ in the middle of the park.
My friend's ka-bunk-a-bunk made me scream like I was being chased by a monster.
