I was chatting with a friend the other day and we both agreed how much we dislike text-speak: You know the C U l8r and TTFN kind of stuff. Neither of us uses it, preferring to spell everything out. Ironic really when I wrote 'Little Book of Chat' which recommends all that kind of stuff. I guess it's for younger people!!
I also hate jargon:
Heads-up (cannot tell you how much I detest that phrase)
Put something on the back-burner
Bandwidth as in 'I do not have the bandwidth for that right now' (I do not have the stomach for that right now so please pass me a sick bucket)
I know that in certain professions jargon is the common language, which is a bit sad but a fact of life. But it IS NOT a part of my life so please do not use it with me.
