a fit thrown by Donald Trump after losing anything, especially a substantive argument on issues or a vote (see Iowa Caucus Feb 1, 2016); often consists of the compulsive and indiscriminate hurling of childish, personal insults, generally void of any substance and fact whatsoever.
I don't think I can handle another trumpertantrum this week. They used to be funny, but now they're getting very annoying and classless. His constant whining and name calling is a real turn off.

When a grown man overhears something mean said about him, and proceeds to go on a poorly-articulated, juvenile rant on Twitter at 3am.
"Did you see that SNL said something mean about Emperor TinyHands McThinskin again?"
"I figured, there was another late-night Trumper Tantrum making the country look stupid again."

the emotional outburst generated by Republican presidential candidate Donald Trump when he has a setback or doesn't get his way. This happened when Fox refused to exclude Megyn Kelly as moderator for one of the Presidential Debates, and when he accused Ted Cruz of election-rigging after coming in second place for the Iowa Caucaus. This term was originally attributed to Ted Cruz and does raise some interesting questions regarding the emotional fitness of one candidate to be president. Let's face it, Trump has no emotional filters! How presidential is Trump? The term is a compound word pun on Donald Trump's last name ("Trumper" for "temper") and and "tantrum."
