short for: what you up to. used mainly by brits.
hey bitches! wuu2?
What you up to?
What are you up to?
What are you doing?
One of the worse msn phrases to use.
meening: What you up too?
young 10 yr olds use it seeming that there cool
but there just to lazy and thick to type the phrase
It tends to piss people off alot
So i suggest you dont use it
