Paarrrrrrpppp
The loud, obnoxious laugh you make when someone makes you feel like a total idiot.
My friend had a paarrrrpppp when I told him I thought the sky was green.
My brother had a paarrrrpppp when I told him I used glitter for a math test.
My cousin had a paarrrrpppp when I told her I tried to write with my toes.
