Glow Worm 

When a person squints his/her eyes in the same fashion of the 80's stuffed toy with a hard plastic head that looks like a worm stoned out of his mind. While doing this one must draw in very close to your partners face and stay their till they acknowledge that you are doing the "Glow Worm".

I want to Glow Worm you till you can't take it any more!
