Hrrr can have many definitions. It is a bird-like (toucan) sound derived from an extremely snobby, high maintenance woman with a large noise. Hrrr has been developed over the years as a sign of judgement when a person, place, thing, or event is considered trashy or poor.
You may also Hrrr when you feel better than someone, example "I am in my new lexus with my new Louis Vuitton going shopping and to starbuck, Hrrr!!!"
I just got a new iPhone4, I see you are still using the iPhone3, HRRRR
