oa 

In switzerland there's a famous rap-group called oa.
Somehow they managed it to make people say oa instead of awesome, fresh, good, cool etc.

so when you get to switzerland make sure, to know the meanings of "oa". (adjektive)

Man those guys look good, they look so oa!

Don't act oa, we know you're no good.
