I do say 'sort of' a lot. Also 'cool' and 'no probs'. I NEVER say 'mate', 'footy' or 'bonza'. I do use the word 'lovely' a lot and start a lot of sentences with 'Yeah well...'. I also like (appreciate) the phrase 'That's crazy talk' and make obscure quotes to obscure things where only I get the joke and then giggle incessantly to my private joke while others look at me quizzically...
I use gosh a bit, and I generally appreciate a smattering of Enid blytonisms from time to time, pretty is a nice word. I often make jokes that only I get, I try to convince myself that it is my superior intellect, but may likely I am just not funny.
