Maybe it's just me, but it seems like lot's of people have begun enunciating "str" as "schtr."
Almost as if they have a flattened tongue, that waggles back and forth in their (pardon me for my politically incorrect indiscretion) "Texan" jowls.
It happens all the time on CNN...golfballs in the mouth: "a schtrong hurricane."
Local channels in Oregon: "it's gonna be a schtrong storm tomorrow."
Bloomberg: "There's a schtrong upswing in oil prices."
Like, I'm looking for a really "schtrong nuculear blast" tomorrow.
Forgive me...I'm just a pronunciation freak. LOL
