bite you on the leg

The phrase bite you on the leg came into use to describe predictable behaviour of known trolls on troll-friendly large public wikis. While it was unpleasant and uncomfortable, this behaviour, it was not in general fatal nor harmful in the long term, and was a nicer way to react than to disappear or begin to fight actively for power.

It has since been absorbed into troll culture in general, especially as it seems to correctly describe the behaviour of endangered species who have just been saved from extinction, and have begun to regain their vigour and health. See also Crocodile Hunter.
