When you're confident about something to the power infinity you answer with a Yuush.

For example :
Pessimist : Are you sure YOU can do this?
You : Yuush ! Is there even a second thought to it ?!

Yuusuke Urameshi 

See also, Yusuke Urameshi, alternate spelling.
Leading character in FUNimation's Yu Yu Hakusho, Yuusuke was a juvenile delinquent who traded his life to save a little boy in the street from a car, and in turn got a second chance from Spirit World to prove his worth.
He became the Spirit Detective of Earth, and as such was forced to fight a bunch of demons in a bunch of different situations over 100+ episodes and two movies.
In love with Keiko (also spelled 'Kayko' in english versions), best friends with Kuwabara Kazuma.
Yusuke loves a good fight, is too stubborn for his own good, and somehow manages to survive, even when he has no idea what he is doing.

Kurama: "So you didn't have a plan after all. I think I'm starting to understand how you work..."
Yuusuke: "Hold on, Kurama! What's THAT supposed to mean!?"
Kurama: "I means what it sounds like..."
