An American slang
term that bears no relation to real Spanish, but is used widely in films and TV shows.
The correct Spanish
No hay problema
; No hay de que; Ningun problema; No te preocupes, etc., etc., but NEVER "no problemo
," which makes the speaker (or film and TV script writer) sound provincial and ignorant.
, can I borrow your car?"
"No problemo! (usually uttered with an annoying surfer-dude or frat-boy tone).
