An absurb statement or series of statements with no basis in fact uttered or tweeted by Donald Trump, often at 6 am during his already scheduled dumping times. A Trump dump may not be retracted until after more than 5 years of assertation without any evidence (see: Obama's birth certificate), or may just pass into nothingness after the media frenzy is complete.
Have you heard about the latest Trump dump? Apparently Big Bird is really a nazi propogandist!

A lighthearted reaction upon receiving disappointing news of some sort. Usually something that isn't a particularly a big deal, esp. when it primarily affects someone else - sort of a mild schadenfreude. Sometimes doubled or tripled, and possibly said in a sing-songy voice for added comedic effect to imitate a muted trumpet, which is how the meme originated.
