I wonder if the lead vocalist of L7 was quoting Karen Finley –
from Wikipedia –
During their performance at the 1992 English Reading Festival, the band experienced “technical difficulties with their audio equipment” and were forced to stall their set. Quickly, the rowdy crowd grew restless and began throwing mud onto the stage. In protest, lead vocalist Donita Sparks removed her tampon on-stage and threw it into the crowd yelling “Eat my used tampon, fuckers!”. Sparks has remained unapologetic about the incident. This has been referred to as one of the “most unsanitary pieces of rock memorabilia in history”.
