Flexitarianism

During his time in Camelot, Rory Williams described himself as a flexitarian, as he "[didn't] always eat meat". He used this as a reason to refuse food by a campfire during the Quest of the Green Fire. (AUDIO: The Glowing Warrior)

Behind the scenes
The term "flexitarian" for only occasionally consuming meat was derived from vegetarianism around the 2010s. It was added to the Oxford English Dictionary in 2014.
