We all have one word we say way too much. For some it's like, for others it's dude and for the sickies, it's typically feltch. Bill Self apparently likes to say "butta" a lot. He says it almost as much as I say, "yeah, yeah, yeah." That's what you say when someone's describing something to you and you have no idea what they're talking about but you say it to keep the conversation going.
