Etymology

Origin of boa

1350–1400; Middle English < Latin: water adder

Explanation

A boa is a type of snake that squeezes its prey. It's also a fluffy, feathered, colorful scarf. Don't confuse the two and wear a snake as a scarf! There are two types of boas: one is usually dangerous, and one is sometimes fashionable. The boa is a type of enormous serpent (also known as a boa constrictor) that squeezes its victims to death. Boas are mainly found in tropical regions. If you see a boa outside a zoo, you're in deep trouble. The other type of boa is more silly than scary: it's a long thin scarf that has either feathers or fur. If you are shopping for a boa, try to avoid coming home with the reptilian variety.
