An extremely socially-awkward person, that rarely involves themselves in the coversation and only contributes to the conversation by randomly commenting with a semi-muffled mumble (this usually is followed by a very, very awkward silence within the whole group of people).

When the person you're talking to is mumbling and you can't understand a damn thing they're saying. Usually used in situations where they're giving you important information like a reservation number or directions on how to get somewhere.
A typical mumblefuck conversation.
"Can I get your order please?"
"Yeah-um...I'd *mumble*...and then *mumble* large *unknown stammering*"
"I'm sorry, what?"
"Hey, Amy, how do we get to your house from downtown?"
"You'll go down *mumble mumble mumble*...after that you'll take a *mumble* onto 4th *mumble*
"Hold on, Amy, just a sec....Guys, can you shut up for a sec, this is a real mumblefuck conversation and all your talking isn't making this any easier to hear."
