Host: Person who will host the event and is required to provide an appropriate level of stereo equipment, older vintage gear with CD/MP3 inputs is most desirable. The Host defines acceptable music and attire at the event. I.e., participants should remove shoes before entering; this is known as the "Dawn Rule", invocating "The House of Slippers" designation for said location.
Penalty Flag: This happens when music violations occur. Acceptable music is defined by the Host or by a majority of the group; the Host has absolute veto power.
Penalty Shot: Offenders of the music violations are required to have one shot of quality Tequila per incident. Additional Penalty Shots can be levied, compound infractions can and will occur.
Each person will take orderly turns playing a single song and is responsible for knowing when it's their turn; ensuring that the previous songs are ended appropriately. Ending songs prematurely, music over-runs, miscued selections and lateness will result in a Penalty Shot.
It is customary to end with a meaningful song; a selection from Ted Nugent is preferred.
I would say... that was an stereonight !
