cant stand 'my bad'.
but i admittedly say things like 'cheers' all the time. i hang out with a bunch of brits in nyc, and it nicely rubs off. but i dont use the word holiday for vacation and needless to say they make fun of me for not using 'proper' vocabulary
. cant win!
and the worst is "she's all - or he's all" (instead of she said) - its not said that much here, but in california i heard it enough.
and the word 'like' at any time when it definitely does not need to be in there.
phrases i cant stand online - anyone that uses the word 'definitely' and can't spell it correctly.
