1. Ricky didn’t come home on time from his friend’s house. When he got home, his mother tanned his hide.
2. That child is disrespectful and uncontrollable. What he really needs is for one of his parents to tan his britches.

The expression originates from the practice of tanning (preparing) animal hides (skins) for use as clothing or shoes by hitting them with a tanning instrument. Hide is also a slang word used to refer to a person’s skin. The alternative britches (pants) refers to the fact that a person gets spanked on his bottom. The expression is usually used to describe how parents might punish their children.
