swirly(1990)

[Sam Clements]

A _swirly_ (swirlie, swirley), at least in the US, is a few bigger boys picking on a smaller kid at school and holding him upside down over a toilet and sticking his head in the bowl and flushing.  

I can find a usenet cite from 1990, but it should be older than that.  Nothingprior  in our archives, not in OED(that I could find), not in M-W.  Not in newpaper archive(that I could find).  DARE ends before _Sw_ .

No doubt a movie/tv skit from before1990 used this, but I don't remember one.

Any help?
