YY to "teddy" when it's not a bear.
"Plate up" instead of "dish up" - I think I've only ever seen this one on here!
"Baby names" - very widespread, but illogical because names are usually for life!
"Passed away"
"Bad" for injured, e.g. "he's got a bad knee"
"Poorly" - I prefer "ill," or if it's something really minor, "not well." Particularly dislike it when someone says someone is "really poorly" when they actually mean they're dying - it sounds as if it means they've got a worse than average cold or something!
"Pooch"
"Kitty" (as in cat - it's OK if you're talking about pooling your money!)
"Baby" for someone who is clearly a toddler
"Telly" - but it's worse when people spell it "tele" - my mind wants to pronounce that "teal!"
"Store" for "shop," if the speaker is not American. Seems to be common in shops themselves now, loudspeakers announcing that the "store" will be closing in X minutes.
And come to think of it - "close/closing." I'm definitely BU here, there's nothing wrong with the word in theory, I just don't like it as a collection of sounds.
