To creep or steal away privately; to withdraw meanly, as a person afraid or ashamed to be seen; as, to sneak away from company; to sneak into a corner or behind a screen. You skulk’d behind the fence, and sneak’d away.

To speak roughly; to talk in rude murmuring terms. It is malicious and unmanly to snarly at the little lapses of a pen, from which Virgil himself stands not exempted.

To hide.

A mean fellow.
