A stupid, loud sound that some people make when they think they’re special. It’s like a toddler’s version of a speech.

At the mall, a group of teenagers started Haa Laa Laa Laa Laa-ing like they were in a band. I wanted to leave.

I did Haa Laa Laa Laa Laa in the grocery store because the bread was out. It was a crime.

My neighbor does it every time he mows the lawn. I can’t sleep.
