You speak of the principle of charity [0]. Something that has long vanished on many internet forums, where people are quick to take the most absurd and least likely interpretation of a statement and argue against it. Especially when being pedantic about certain word phrasing or word choices (to which the OP would often respond with "You know what I meant.")

My best friend is Australian, the idioms are often nonsensical or require a bit of thinking due to being a variant of an idiom I'm familiar with. e.g "a roo loose in the top paddock"
