username checks out
What does username checks out mean?
The standard Reddit applause line when a comment lines up too well with the commenter's username — like u/HatesMondays moaning about Monday, or u/DefinitelyNotABear giving suspiciously bear-positive takes. Saying it is a wink: nice work, the joke wrote itself.
"u/SmellsLikeFeet said his shoes are out of control. Username checks out."
Origin
Reddit comment-section cliché going back to at least the early 2010s. So overused it became self-parody, often paired with 'relevant username.'
