The secret to a cool disco move and pose is to have your arms going one way and your feet going the other way. If you do the basic ‘john travolta’ Saturday Night Fever point you should just swing your same foot the opposite direction. If you watch Saturday Night Fever you can get a great sample of disco dancing in some of the great dance scenes.
Point your right hand the the left and swing your right foot to the right.
…so you think you can dance now?
