Particles of light or other electromagnetic radiation.

A person with an outwardly dominant, masculine, or aggressive personality, but who also enthusiastically takes on the submissive or "bottom" role in the bedroom.

A wave (or particle) that makes up electromagnetic radiation, or 'light.' This particle is also the quantization of the electromagnetic force. A vibrating electron will release a photon.

Scientists are still not sure whether photons are particles or waves. In reality, they have characteristics of both, leading some to suggest that they are particles which ride on an electromagnetic wave like surfers. One wonders what would happen if they fell off their hypothetical surfboards.

"Photon" is also used in The Hitchhiker Trilogy as a curse word, as in "What the photon is it, Ford?"

A replacement for the word 'fuck'. Origins are traced to the increasingly misnamed Hitchhiker's Guide trilogy.
