It usually happens to a female; when she orgasms so great that the pulsating that is happening in the vagina begins to take over her body till her whole body is gently spasms while she orgasms. It usually requires lots of foreplay and relaxation.

For a woman, it occurs when she orgasms with clitoral, g-spot, and breast stimulation all at the same time.
The full body orgasm is so intense that it feels like you're almost having a seizure. Most easily done with girl-on-the-top position. Bonus points for achieving it!
