My personal opinion on how it went:
Trump Aide: suggests Dana White
Trump: “You mean the wrestler?”
TA: “nono” explains who Dana W White is
T: dreamy eyes “You know that Dana White is a huge guy, massive. Almost as big as me, when I was younger. And so fit! You know I love women, everyone says it, 'Trump loves women,” but a strong virile man like that? He wouldn’t take any shit from the fake news press pool. He could strong arm them, literally I mean this guys arms are so big."
T: calls Dana White for job offer
Edit:
Oop, I was right, I think.

Most new words start in socially isolated communities and radiate outward as those outside the community are exposed. Generally this also causes a loss of original context that can lead to a drift in or loss of meaning from the original use in its origin community.
Both based and maxxing come from the alt-right / incel community originally, I believe.
Linguistics Nerd on YouTube has good videos on the origin of many modern slang words.
