The Mooning of Amtrak is annual event in which thousands of participants come to bare their naked butts to the Amtrak train. This takes place in Laguna Niguel, California.
An erection caused by the arousal from the mooning of another person.
You can’t help but masturbate as long as the other person keeps showing his/her ass, a.k.a. full moon.
The perfect retaliation after being mooned. The victim executes a (flying) kick at the mooner.
A direct hit indicates the perfect revenge.
If the victim misses his kick, the mooning counts as twice the humiliation.
Alexander: You got mooned yesterdag, didn't you?
Robin: Don't worry, afterwards I performed a flying mooning-kick.
Moe: But I dodged you!
Daniel: Whaha, double mooned!
robin: Oh, dear.
