habbledabble
A stupid noise that comes out of your mouth when you're trying to be cool, but you're just being a fool.
I did a 'hobbledabble' in the middle of a video game. I lost the game.
My mom said 'hobbledabble' during a Zoom call. My dad laughed so hard he spilled coffee.
I said 'hobbledabble' to my crush. Now I have to go to the cafeteria alone.
