I've seen a number of network news reports in the past about parents disturbed on moral grounds by their teen-aged kids booty popping at proms. Booty popping in Fairy Tail, however, seems to be an actual crime, as seen by the episode title card in the image.
If that episode title doesn't make you chuckle at the very least, call the coroner and have yourself declared legally dead. Enjoy!
