As a newbie I don't know if this has been mentioned yet and I can't be arsed to look!
After the onsaught of the word "like" which drives me insane. All of a sudden everyone started answering a question with "so" as a prefix. This is not just the proles, this seems to be universal - even presenters and educated people on Radio 4 - even professors!! (SHOCK HORROR) Bloody Americans! Bloody stupid British, having to copy every sodding thing they do.
