Hadoo

The default word to yell when someone walks past your screen during a tense moment.

So I was playing metal gear solid and then my bro walked in the way while I was about to shoot someone so I yelled "HADOOOOOOOOOO"

HADOO

When an individual makes a sudden jolt or quick movement.

"We just got a 20 bomb. Make that left quick, HADOO HADOO"
