a willi
A willi is a tiny tornado in the outback that lasts like five seconds and makes you think you're in a wind tunnel. It’s not a hurricane, it’s a willi, and it’s tiny and annoying.
@outback_willi: Just got hit by a willi. I’m now a tornado in a hat. #williattack
My cousin ran into a willi and got sand in his pants. He looked like a ghost. #williexperience
I saw a willi and it nearly blew my hat off. #williweather
