Pronounced in a similar way to whooshka - except the 'wh' is silent hence 'ooshka!'.
Has several uses:
1. Same use as whooshka!! -
declaration of joy.
2. Declared when you see a
hot chick - misuse of this on a non-hot chick is sin.
3. Randomly shout this at somebody when
you're in a drunken state to give them a shock and shitstir
