Facebook introduced the verb to “friend.” Chatroulette has introduced “nexted.” When two strangers meet randomly face to face either one can “next” the other, immediately, or at any time in the conversation. The NEXT button terminates the meeting and brings on the next stranger. If you are not female, or over 30, you’ll most likely be nexted without remorse. In fact on old guy like me will treat any encounter that is not nexted as a victory.
To “friend” someone as in linking them to an account has been around far longer than Facebook. LiveJournal used the term when I signed up on it in 2002, and it was around much earlier than that.
