Habhab - Habhab is that annoying thing you say when you're too tired

Habhab is that annoying thing you say when you're too tired to think but still too high to sleep.

I said 'Habhab' at 3 a. m. because I was eating cereal and watching my brother's old videos.

My sister said 'Habhab' after I threw a sock at her head.

I said 'Habhab' because I was confused and my phone was broken.
