[plz]

can anyone tells me

[•N•a•d•d•y•]

uh well it's hard to explain, it's an expression, it's like "it's okay" or "no problem", sorry if I'm no help, some things are hard to translate

It depends on which contex the word is. if u say thanx to someone and he replies wallaw it means like naddy said dont mention it ; no problem .but sometimes it comes in another contex and it means: Shame ; how dare u; how could u....u know its hard to explain but its something like that.Hope i helped a bit.
