Camp (style)

The Ninth Doctor explained to Rose Tyler that, while humans used the colour red to signify danger, "everyone else" saw it as camp: "All those red alerts, all that dancing." (TV: The Empty Child)

Behind the scenes
In NOTVALID: The Curse of Fatal Death, the newly regenerated Tenth Doctor mockingly identifies the Master as "the camp one", alluding to his "Dalek bumps" which had been refered to as breasts.
