The president offered Americans a bit of levity on Wednesday morning amid his broadsides about the Russia investigation and complaints about fake news, closing out a busy day of tweeting with the message, “Despite the constant negative press covfefe.”

Though it spawned some amusing responses, the tweet was not appreciably stranger than most of the president’s tweets, which frequently feature misspellings, unconventional capitalization and unusual use of quotation marks. In fact, the “covfefe” gaffe was just the latest of Mr. Trump’s tweets to bear an uncanny resemblance to certain strains of absurdist Twitter comedy.

Sometime in the early 2010s, a style of humor marked by bizarre spelling, grammar and subject matter became popular on Twitter. Ultimately known as “weird Twitter,” it was tough to define — talking about weird Twitter was a surefire way to get made fun of by weird Twitter — but easy to spot. Practitioners included @dril, who remains anonymous, and Patricia Lockwood, a poet and the author of the recent memoir “Priestdaddy.” Along with @horse_ebooks, an account that tweeted seemingly random but frequently entertaining snippets of text, the weird Twitter comedians presided over the emergence of a new and ridiculous form of humor.

While the heyday of weird Twitter is probably over (the form may have reached peak awareness in 2013, with an oral history by John Herrman and Katie Notopoulous at BuzzFeed), its spirit lives on in high-concept humor accounts like @SICKOFWOLVES, the online performance art of Chuck Tingle — and, most oddly, in the early-morning missives of President Trump.
