Papxillonian mylo-burper
From Tardis Wiki, the free Doctor Who reference
The Doctor believed that Papxillonian mylo-burpers had "the most annoying way" of interrupting conversation.
In his letter for the first issue of Doctor Who Weekly, the Fourth Doctor noted that all his back-and-forth time jumping would confuse even a Papxillonian mylo-burper. (PROSE: A Letter from the Doctor 1 [+]Loading...["A Letter from the Doctor (DWM 1 short story)"])
