Commonly mistaken as a "cute face", :3 is actually a symobol used when you want to Tea bag someone.
*Tea bag - To perform the tea bag, have the girl lay flat on her back. Then you squat over her with your hands on your knees, and gently dip your nut sac in and out of her mouth in a motion similar to performing some kinda fucked up yoga exercise. (curtesy of Dirty Provebs dot com)
<Lethal> Why do you always stick my balls in your mouth? :(
<h0r> Because I love to be tea bagged!
