Color coded wrist bands you bring to any party, concert, scene etc that you hand out to girls based on what you want from them. Like kiss, spank, cuff, tug, suck, fuck, anal, etc. That way they all know who is on board for the night.
"Hi. Can I have a kiss?"
"Sure."
"Here's a color coded wrist band. Hold that thought."
"Why don't we go up to my room and fuck?"
"Great idea. Here's a color coded wrist band. There's some girls I want you to meet.
A group of people in a marching band (typically girls and flaming homosexuals) who spin and chuck into their 6-foot metal poles with 4-foot silks, wooden/plastic rifles, and unsharpened swords (sabres). These people are the most badass people in the marching band. No one fucks with the guard. They are some of the most talented people in the band. They also never have any free time due to marching band and winter guard.
Person 1: Are you free tonight?
Person 2: No, I have colorguard.
