When you are in the middle of having a chronic orgasm. This can occur anywhere to 2-80 times a day. Make sure to always keep extra towels or blankets (if you get extra wet) with you wherever you go. To help calm this down carry some cum down with you to help regain control of your vagina or penis.

Music so good it could elicit sexual arousal.

What you say when you or a friend gets a boner i.e. a hard on i.e. an erect penis i.e. an erection.

When something is happening "it's happening". This can mean a lot of different things. To put it into perspective it is usually something that is positive. On "My name is Earl" Joy tells of Earl's weird habit of waving his arms in the air shouting "it's happening" during an orgasm. Furthermore, before I ever saw that episode I was traveling home with my friend Rachel from a camping trip and I warned her blind a** of a bird in the road about 20 feet ahead. She said "it's happening" and sure enough feathers flew everywhere.

And spiritually speaking: Breathe, Believe and Receive. It's all happening.
