A character from the Doctor Who spin-off Torchwood. He's the "tea boy" of the Torchwood hub. He cleans up after them, gets them everywhere on time, and looks good in a suit, to quote Captain Jack Harkness.
They meant to kill him off during season one, but the audience liked him so much, they decided too keep him.
He is also head the the cult King Ianto's Coffee Club, which is trying to replace tea with coffee as the official drink of the UK. Once he comes to power he plans to off Owen, yay.

Noun: a friend who is usually only called upon by a friend when a more primary/prominent friend is unavailable.

Taken from the term “second string” in an athletic competition situation. In football, if the star quarterback gets injured during a play, the second string is called off the bench to replace him/her. A “Second String Friend” is essentially benched until needed, if ever.

Synonyms: Plan B, Second Choice, Secondary Friend, Benched Until Needed
