When your Cam4 show is posted on 4chan for all the world to see, thus leading to embarassing conversations and awkward moments. The same goes for any other sites where one is willing to be nude on a live webcam feed.
Guy: So, you like to get naked on camera for strangers, huh?

Girl: Oh no, I've been 4cammed! This is so embarassing!

See 4chan.
