idioms are disappearin'?

Yo baes, do you think that idioms are disappearin' from da English language yo?

And more importantly yo, how come no NEW idioms are eva thought up yo? All da idioms dat ya see are da same ones from yonks ago, no one eva comes up wif new beef al. Why dat yo? Can anyone give me an example of a new idiom?

Peace out bae!

I can give you an example an idiot... its you..!! never mind your idioms learn how to write you prick..!!

Bae, dat's not nice. I'm just askin' a simple question yo, how come you gotta get all pissed wif me? I know how to write properly, but I don' see da need on dis forum al 'cos it's not necessary yo, you reckon dis is an academic report or somfin' eh? No, dis is just a random as forum al. Why shouldn' I write like I speak wif da whanau, I'm lettin' ya be my cuz, you oudda be proud of dat.

So can someone give me an example of a NEW idiom?

What's the difference between new idioms and new slang?
