A sparkle party is full of lots of hardcore things, like party pants, dancey dance, sparkles and the like. The music playing at said party will probably be a techno-dance blend. Classical pianists are known for their secret love for dance music.

"I had such a kickass time at that Sparkle Party last night. Glad I wore my rubber boots and party pants for dancey dance!"
