unofficial signals

[Hartsy]

A bit of another thread got me thinking about some things NOT to do on the court. For instance, the "toilet bowl" signal. I never noticed it too much until I realized it had a name, now I laugh whenever I see it used. The other one mentioned was the traveling signal for a violation on a spot throw in.

I thought it might be interesting to hear of some other mechanics, signals, and things such as that, that should be avoided. I look silly enough without trying.
