SMS lingo: convenience vs. formality

"Iv bi stupd iVe bin cln u on ur old numb sory bout dat" for 'I have been stupid I have been calling you on your old number and sory about that. As for this one, you will figure it out yourself , "hi ts Karly de O.G Negar, ths z ma no. If T's no aint workin halla @ dis no.peace!"

That is SMS text messaging language for you. It is here and it is here with a bang. Its cool, its streetwise, to some extent its smart.  "At times I hook up with a guy right, then he texts just as am about to go to bed to say night. The way he texts makes all the difference. I can easily tell I cannot relate with this one from the way they text", 24 year old Karabo, a University student says.
