OH lest we forget * Proper English is verbalized in the U.K. However In Usa they verbalize "American" English which no doubt is mostly slang .... @ Least In the U.K. one can pellucidly understand a sentence the 1st time.

Furthermore:
American English is not my primary language and for the most part I optically discern it as floating between jocose and perplexing, Rarely is it straightforward and in simple.
