when you say something really stupid and someone says "That's a neck!" Ya might wanna say 'self serve', 'soft serve' or 'mirror'. Self serve is when you do it yourself, soft serve is a light slap in the neck and mirror is when you do it to the person who said "that's a neck". A neck is when you slap the shit out of their neck.
