(I'll help ya, "let's go Brandon" refers to a chant at a NASCAR race of "fuck Joe Biden," to which a newscaster covering the event tried to be slick and say was actually "let's go Brandon," as one of the racists drivers in the race's names was Brandon, and then in response it became a meme mostly for the right/republicans. I'm personally surprised to see it being referenced above, as most people have spent the last few years decrying it as a nazi dogwhistle, but I'm curious to see if it now widens in popularity as people start to admit they never liked Biden either.)
