Sometimes you hear people say something like "I call [noun]", mostly with bullshit ("I call bullshit"; and there's also a question on the site with shenanigans). It feels like an opinionated statement about a situation but I don't find it clear whether this is based on to call someone/something out, on to make a call (like when a referee makes a call in sports), on the idea that the person is naming (calling) what they see something (I call that (thing I'm seeing) [noun]) or even on the idea that someone is speaking their mind bluntly about something (maybe subsuming the expression call it as one sees it?).
Of course things like bullshit or white trashery are noncount whereas shenanigans is seemingly almost exclusively used in the plural form except when modifying a plural noun (for instance shenanigan tactics) or when identifying a list of things which might be called shenanigans (for instance shenanigan no 1). In so many words it's not clear whether the plural form used with "I call" is plural because it's mostly used in the plural form or because the construction is idiomatic with the plural form. So with a countable noun I wouldn't know for instance whether I should say "I call (a) double standard/standards" or if using an article with the singular form would make this ambiguous as if the expression was in fact the head of a sentence about some personal definition of a term (I call a double standard something that...).
- What meaning of (or phrase based on) to call is used in "I call [noun]"? Is it useful to ascertain that or do you see each example as a set construction with a noun that is not really related to the core meaning of the verb: if so what does "I call bullshit" mean?
- When the noun is countable, which of the singular or the plural form is more idiomatic and if it's used with the singular, is a determiner required/possible; or is it just about usage: if so do you consider "I call double standard", "I call a double standard" and "I call double standards" equally idiomatic?
