So, "we went out drinking last night and got drunk" is incorrect English, in your opinion? "Got" does not only mean "received." It also means "became."Another way of putting it would be "we were cut off", as "got" is the past tense of "get" which means "to receive". Although "got" is used often in UK English, it is not "perfect" by any means.
Colloquial speech can be quite rare, confined only to one small region of a country. We recently had a thread with "I need my watch repairing", which is apparently a construction that is often heard in Northwestern England but nowhere else.Incidently, the use of "common" alongside "colloquial" would seem superfluous as both mean "informal".
