This short 2.6-second clip is two high-pitched voices screaming together in a long, panicked 'Aaaaaa', with one voice slightly overlapping the other as the panic rises. It feels frantic and over-the-top, like two people realising at the same moment that something has gone badly wrong, and that shared, helpless panic is what makes it funny as a reaction.
