look up any word, like rito:
 
1.
An expression used to connote:
1. the act of something stupid,
2. something really lame,
3. something obvious.

The 3nd meaning is used closely more like a synonym for "Duh!"
1.
(Person 1) I just fell from my bike, after attempting to make a 360 on bike

(Person 2) Urrrrr, stupid.

2.

Are those shoes with little lights?
Urrrr, how lame! That is so yesterday.

*With emphasis on the rrrrr, but not to much as in roawr, kind of like DUH*

3.
(Person 1) Are you coming for the weekend? You said you were... o_0

(Person 2) Urrrrr!

*Again, this time like DUH!*
