Did you?! 

Derived from baseball dialogue, specifically the New York Yankees, 'did you?!' is a question to reference the certainty (or lack thereof) a player had that his hit was going to be a home run. However the same term can be applied to any situation in which one stumbles upon good fortune, or in which one has a commanding performance or feat of accomplishment.

Derek Jeter hits a home run off the end of his bat that bloops over the wall

Returning to the dugout, Nick Swisher jokingly asks, 'Did you?!'

Derek smiles, shakes his head, and walks by

Returning to the dugout, Nick Swisher asks/proclaims, "Did you?!!"

Did you know 

Although phrased as the start of a question, it is actually an introduction from somebody who wants to impart information. It’s used quite a lot by some teachers but it usually comes from somebody who wants bore your arse off telling you things you don’t need to know, don’t want o know and which are less interesting than the sex lives of Venusian bacteria. It’s usually impossible to get away without committing murder unless you can comeback with something that stops them in their tracks and allows you to escape.

Did you know that if you rearrange the letters of “Happy Christmas” you get “Crappy Shitmash”?
Yes, and if you rearrange “Merry Christmas” you get “Mr Mrs Itchyarse”.

did you see my bag? 

Phrase popularized by Korean-Pop group "BTS" in their 2017 classic hit song "mic drop". The bag refers to their accomplishments and the question is asking whether or not their doubters and antis saw it; because if they had, they would realize that they have nothing to doubt.

Person 1: BTS sucks
BTS, in their hit single "mic drop": did you see my bag?
