Laldy originally was a noun for “a beating.” One could get a laldy, meaning “get a beating,” or give (gie in Scottish) a laldy. It could also signify more generally “punishment” and was sometimes rhyming-reduplicated ٴlaldy daldy.
At least by the 1950s, giving it laldy (or giein/geein it laldy, in Scottish) became a way to say “doing something with great energy or enjoyment,” e.g., The singer was giving it laldy all night.
