Ash Hylka Rager
When a group of people, usually teenage girls, go into a room at a party, turn off all the lights, turn on a strobe light, and play LMFAO at top volume. The room then turns into a mini Rave. Hilarity ensues.
Last night after my friend's graduation party, we had an Ash Hylka Rager. We jammed our fingers and hit our heads, but it was soo worth it.
