A person, often a fan of some British-based series such as Doctor Who or
Harry Potter or Sherlock, who is to
British culture what a weeaboo is to
Japanese culture - that is, they want to be so engulfed in English culture that they shit the Queen.
Mark is such a teaboo. I mentioned
Doctor Who offhand when I was next to him, and Mark
instantly rattled off his theory that
Severus Snape was a Time Lord while drinking two liters of Earl Gray. Then he sped off, but not before whispering in my ear the URL for his tumblr page.
