guffbag 

Someone who suffers from severe flatulence and is generally unpleasant to be with in confined spaces.
Someone who is a filthmonger and doesn't wash regularly.
A sleeping bag, the smell lingers...

"Look dude open the window and please give us some notice, your a filthy guffbag!!!"
"We're all set for camping I've got the tents and the guffbags and the flashlights..."
