"What about these idioms? Are them in fashion or out of fashion?"
"17. Mind the step. 18. I'll get it straight away. 19. Mind your head."
"These three are strictly Hiberno-British. You might catch a Hiberno-Britophile like Tony Cooper using them, but otherwise they aren't used by Americans (this statement is subject to the Truly Donovan Proviso)."
Nah. Us real Hibernowhatevers say:
17. Mind the step, ***, or ye'll be *** over teakettle.
18. Me get it straight away? It's your feckin' call, isn't it now.
19. Mind that great, thick head of yours, ye eejit.
We talk that way around our house all the time.
