Specifically people who constantly either make dumb jokes, or attempt to continue a sentence on TV in an effort to seem shocking. Or who when seeing something on TV will say some stupidly sarcastic quip after and then expect your attention. Or even people who give a running commentary on there lives, to themselves.

Typing words is exempt.
Singing is not.
