While straining to remain apolitical with this response, I would be remiss if I didn't make sure that the answer "covfefe" be include here since you're asking specifically for slang terms.
Ever since May 31, 2017, as a result of US President Donald Trump apparently doing just that or something very similar in effect on Twitter, that has been increasingly called "cofefe," which is the exact string of characters left by Trump and generally gets pronounced "cohv-FEH-feh."
It even gets used as a verb, for example:
"That little socialist was still whining about corporate greed while
drinking a $4 Starbucks, so I covfefe'd him."
"Nevertheless, he covfefe'd."
I came, I saw, I covfefe'd.
