That’s what I heard a young person say to another young person at a New Year’s Eve party I attended. In the ‘old days’ they would have said; “phone me” or “give me a call” or even “send me a text.”
Social networking seems to be a whole new communication channel spreading by word of mouth (or word of pixel, I suppose). And it’s not just associated with young people. You can ‘Facebook me’ too if you like.
