An old American way of speaking to a woman, like "honey" or "sweetheart" used to someone you are not close to — "Sure thing, toots." It belongs to the middle of the last century, and you meet it mostly in old films, comic books, and stories set in that time. Between two people who know each other well it can be teasing and warm, but from a stranger, or from a man to a woman at work, it sounds like he does not take her seriously, and many women find it insulting. Today it is nearly dead in real speech; when it does appear, it is usually a joke about sounding old-fashioned. Understand it, do not use it. Note that the same spelling is a completely ordinary plural verb elsewhere — a car horn toots, a train toots — and that use has nothing to do with this one.
