A word that is said when nothing else can be said, during moments of extreme boredom. Can be used as an explanation, a statement, and an affirmative. Most often used by my friends to indicate just HOW bored they are. Also can be used in an extremely sarcastic tone to mock someone who thinks that a very abnormal activity is, in fact, quite normal. Example: (1) So I had no job...and I was just at home for 3 months, sitting at my computer and being like Yep... Here I am. (2) So Chuck and I finally got done arguing, and just decided to have a knife fight. Umm.... Yep!
