According to police, Christie Valazquez Coura went to Beaverton City Hall to pay a fine with two friends, Brittany Medak and Leokham Yothsombath.
After Coura paid the fine, the three women went out to the parking lot and began twerking, the Oregonian reported.
During the dance party, Medak allegedly began urinating between cars in the parking lot while Yothsombath recorded the whole thing with her cellphone.
A court employee called the Beaverton police and the trio was arrested on multiple charges including disorderly conduct, cocaine and methamphetamine possession, and offensive littering.
