Where does FSE come from?

Funniest shit ever has long been an expression of amusement, including online since at least the 1990s. Shit, here, is slang for any old thing, here the object of humor. The hyperbolic adverb ever serves to intensify the level of entertainment—as does the superlative funniest.

By the 2010s, funniest shit ever had earned its acronym (or more technically, initialism) form, FSE. It appears on Twitter by 2010 and was entered on Urban Dictionary by 2013.
