Derivative or diminutive of sick or ill.

A way of speaking used to indicate sickness in a cute way; amongst friends and family members (esp when small children are involved).

Sicky can be interpreted both as being physically ill, or a mentally warped idea; but the majority uses the word to describe physical illness.
