@mitchellbravo: You're very close with "Titty frost", it's "Titty sprinkles" put through google translater. I don't watch Doctor Who either, I just thought anthropomorphic boobs would be even funnier if they spoke serbian. Does Doctor Who speak serbian or something? Never seen an episode in my life.
@mcnunkee: Pretty sure Doctor Who just speaks straight-up English, though from what I understand of canon he's kind of an alien shape-shifter type thing, so the possibilities are endless, I guess?
I think it was my brain unprepared for the cyrillic and reading it as if it were funny latin letters, and that's the only reason I made the association. I read the ee-sounds as Ns, and the f-sound as a lowercase D.
