Rig - how to spot one

[Chestnutter]

Q in title really. What signs would indicate that a gelding is a "rig"?

Thanks

Stallion like behaviour when in fact he's gelded. Mounting, aggression towards other horses and humans (I should add that I've handled plenty of non - aggressive stallions mind you),constant trashing of fences and escaping, general unsettled, tense body language.
