I was answering smy's question that she sent to my in-box. I don't think it's an abbreviation here. I think it just means, "I just sent you your Christmas card in a text message." "Your ass" is just a familiar way to say "you" (especially between men).
Actually, I just looked it up and this is all over the internet. It means, in essence, that the guy couldn't afford to send a real Christmas card, so he sent one by text message.
just a minute, ı am really confused now, should ı mean that it was sent by phone in the text? or just say "noel kartını az önce yolladım SANA LAN" ??
