Can be a verb, noun, adjective, adverb anything really. Is a racial slur, if someone calls you "Trump" take it as an insult, those are some fighting words.
Meanings: You're a bafoon, racists, a cheeto, an idiot, white privileged, showing some white guilt, immature, ignorant, etc. I can mean anything if you put your mind to it. :)
Ex: Jarold: "YOU TRUMP!"
Karen: "What??? I'm taking this to corporate"
