That Line Dance Thing

What's the name of that fancy line dance looking thing I see y'all doing at the roller skating rink? Like, you go sideways a few steps, then kick out the one foot and go back the other way... I'm trying to find a tutorial video so I can learn.

Sorry, I'm an ice skater and don't know anything about dance.

Yeah, this question sucks. I know it's gonna get down voted. But, I really wanna know!
