I hate it when people talk text, e.g. omg, ttyl, fyi etc. It drives me mad. Using them when writing a text or post is understandable (though I never have), it's using them in spoken conversation that I can't stand. Also, sham (I think that's how you spell it), as in 'Alright sham?' You usually hear this from brain-dead retards with their brand name sports wear and corsas. God I hate spides.
