What is gayger counter?

A scientific instrument used to measure gaydiation from a source of gaydioactive material. This takes the form of alpha particles, beta particles, and gaymma rays.

Most often, the gaydioactivity is measured in Gays. A reading of above gayghty-gayght Gays is very very gay, and you should get the hell away from the source of it.

Also, if you emit gaydiaton, you're super gay plus one.
