I think people like to use the word, "le," so often is for personal amusement when speaking to someone else. Like, as stated as an example earlier, "-le types-" or whatnot. Since, then, it's like the word, "derp." Eventually, if people use it enough, they find other ways to define it and what it means. It's done all the time, even if the word as a meaning that says the complete opposite of its origin, like "bad" meaning "good." For "le", being as it is, it may fall into that same trap with the mainstreams. Maybe, maybe not.
