While there's many legitimate and peculiar use cases where closures make sense when writing properly engineered code, my favorite use is simply abusing them in one-off or ad-hoc code where performance or correctness isn't a concern. Basically just using them as lazy shortcuts to avoid the hassle of argument passing. It's particularly great when you have a function scope that's three or four levels deep, and you're referencing a variable via closure that's in the top-level function scope. Much less work.
