When riot police shoot you in the ass. Its basically a pathetic, non-lethal attempt to disperse a crowd of malcontents. This crowd is usually made up of people who didnt go to school that day. Rubber Bullet Kisses are usually followed by Baton Courtesy.

Internet persona(s) who happens to follow you and you happen to follow them back and maintain communication with and have a mutual liking for eachother whether it be friendship wise, etc. (Mutuals if more than one mutual)
