if your mate is too scared to do something dangerous, like doing that big surfboard jump, or stay out late cos he has to be home for his bird girlfriend or talk to a girl in a bar, you could call him a "woose".

look at the majestic woose gallop across the plains

Don't be such a wuss, stand up for yourself! (not woose)

You are being a woose by not standing up to the fucktard bully.

Oh Woose not again!

"Is is a moose? Is it a plane? No, it's a woose"
"She was such a woose that night"
