Skin Teeth Extremely Film Thin Aaron Dove Dock

Idiom By the Skin of Your Teeth
Example Aaron dove off the dock just as it collapsed and escaped injury by the skin of his teeth.
Meaning by an extremely narrow margin; with practically no room to spare; just barely
Origin This expression, which was first mentioned in the Bible, has been popular in English since about the beginning of the 1800s. Your teeth sometimes have a film on them, especially when you wake up in the morning. If you think of this film as "skin," then you can see that the "skin of your teeth" is thin indeed. If you avoid some terrible calamity by a margin of safety so small that it's as thin as the skin of your teeth, you've had an extremely close escape.
