During the whole Trump tenure, I have seen a bunch of what I would call discrete to very obvious Q hints and references. The most obvious has gotta be a rally speech where he kept talking about the local farmers growing cucumbers. The first time he said it was like 'cu-cumber'.. and then 'cuuuuuuuu-cumber' and then... 'we really love our cuuuuuuuuuuuuuuuuu-cumbers.' Anyway.. that was directly from him and that one stuck with me.
What other ones would you consider obvious?
The one time when Q confirm his tripcode via a zero delta Trump tweet. The zero delta tweet contained every character, case-sensitive of the tripcode.
