Pet Hate - Unfiltered Americanisms

Speaking of dates, one American trend, which thankfully doesn't seem to have spread here, is the way they say dates at the end of tv ads for films.
It was mildly annoying when they'd just say " out January fifth," leaving out the "the" (and if I were being pedantic, putting the words in the wrong order) as that's how most Americans say it.

But then I noticed that they started saying "out January five!" Oh my. Perhaps they're worried that people won't know what "fifth" means, or that the extra letter it has over "five" would be too much hard work to say.

But it got worse: "Out Jan five!" Oh dear, oh dear.
Is January really that hard to say? Really!? "Jan!!??"

I know it hasn't seeped into usage here, but the principle behind it is that of over-simplification, the principle behind most Americanisms, and something that's definitely influencing the way people speak here in a general sense.

I can't stand "Awesome". It's just so wrong coming out of the mouth of an Irish person and a load of people say it. Sick.

"pissed" instead of "pissed off".

"write you" instead of "write to you".

fall instead of autumn
