Usage

What is a Taser? A Taser is an electric weapon that stuns its human or animal target by direct contact or with wired barbs that are shot from the device. The word Taser is a trademark for a brand, but in common usage it is used to refer to any such device and is often used as a synonym for stun gun. When used this way, it’s usually not capitalized (taser). Sometimes, though, it’s spelled in all capitals (TASER). Tasers are typically associated with their use by police. Civilians have also adopted such weapons for self-defense.
