look up any word, like douchebag:
 
1.
When you feel overwhelmed and can't find a word to describe it.
Ooosh what a long day.

2.
slur for o shit
when you drop your cell phone in the rode and your about to get ran over by a car and you really say o shit but the way you say it makes your friend think you said ooosh.
