gah gahs
A warning from a beaver that says if you mess with them, they will come after you with a vengeance and probably poop on you.
The beaver yelled 'gah gahs' at me when I tried to steal his tree.
I heard 'gah gahs' from the woods and ran away because I knew I was in trouble.
The beaver said 'gah gahs' and then I got poop on my head.
