Dancing.... ?to mcr..? terrible idea

so me and my friend made up a dance to NANANA, and were making one up for Teenagers, and i also kinda wanna dance to Helena. The suck, theres part where we dont know what to do.... so maybe ya'll can help out a little. Dont be mad but im a little worried some people (not saying you will) will take our dance and call it there own. is that stupid? i mean, its a dance so shouldn't everybody know it... any ways, tell me what you think.. if it sounds like a good idea and if i should post a video of what we have now.
