glowstick ninja
Noun (Derogatory) - A person who haphazardly whips double-glowsticks or glowropes around in a fashion vaguely resembling the use of nunchaku, with little to no regard of the people or property around them. Frequently responsible for causing minor bruising, spilled drinks or ashtrays, and generally ruining everyone's good time.
Dude, I was having an awesome time at the club last night, until this fucking glowstick ninja came out of nowhere and swung his stupid ass rope into my face!
