When a person who seeks fame uses humour to make fun of a very famous person thus not allowing themselves to have fame.

someone who is absolutely geeky, but is also somehow attractive. It could be their glasses, their attempt at wearing their hair in gelled spikes, or their fashion sense--or lack thereof. They're still sexy in a weird way.

Smug patriotic newsanchorliness. A hidden, invisible but extremely palpable, perceptible Dark Jedi Power possessed mostly by members of the mainstream media, and poked fun at carefully by Stephen Colbert.

Gravitas is difficult to define, but you know it when you're seeing it.

Defining characteristics: a nice round, solid Midwestern broadcast voice; the same suggestive pauses and stresses on certain words and phrases as found in gravitas, such as "terror", "patriotism", "homeland", and "national security"; but the piercing gaze is occasional, fragmented, cautious and discarded, in favor of...
