Just say no, I guess

Just saw these videos, HT: Doug Wilson.

I can remember in the 80's when "just say no" was ridiculed as a somewhat-backward approach to dealing with the issue of drug use. Some of you may remember that as well -- some of you weren't out of diapers yet, so you won't have any grasp of the events in question.

But in order to stem the broad use of the phrase "that's so gay", apparently it'll do just fine -- or its cognate "knock it off" will. Perhaps it is a more-earthy rendition. "Just say no" sounds so earnest and clean; "knock it off" is more, um, something.
