A popular form of adult entertainment across the US. Performed at strip clubs, aka nudie bars.
The dancer (generally female) dances to music while removing her clothing. The guys stare, drool, ogle, and then give praise through green pieces of paper.

However, this practice is now illegal due to a recent Supreme Court ruling. The Court ruled that a dancer must be minimally covered in specific areas, by a 6-to-3 vote. The ruling is an attempt by the Supreme Court to regulate a moral issue, and to stifle crimes that are inter-related to "stripping", such as prostitution.
