An awkward pause in a good conversation in which both of the people run out of things to say and are are frantically racing through their heads to find something interesting to talk about. Once one of them finds something to say, its usually just plain random and not connected to the previous conversation in anyway.
Person 1: ...And the next thing you know, the n*gger started jumping him for his hotdog..
Person 2: ..wow that sucks......
~l o n g p a u s e~
Person 1: so.. what gaming system you got?
Person 2: ....*sigh*...we gotta come prepared with stories so we won't have that uncomfortable conversational pause..
Person 1: right.
