Sarah's sudden appearance at work in a pair of tights caught her co-workers off-guard, who were surprised that such a sensible woman had bum delusions.

A large number of people of the homeless persuasion gathering together in one place. They can usually be seen massing by bridges or wherever there are cardboard boxes to be found. Usually travelling in packs, when you see one member of this brigade you can usually find the rest. Markings include layers upon layers of winter coats, which aid in escape when confronted by predators by creating a mass of confusion, much like zebra stripes.
Some guy: Dude, I saw a trail of winter coats leading down to your block from the train! What the hell happened?
Some other guy: O that's nothing, the bum brigade was passing through. I think they migrated.

I wouldn't go in there if I were you, Sean's just been in there and got Bum Pepsi all over the back wall
Karen has been ill for weeks bless her, I didn't have the heart to tell her she's got bum Pepsi all up the back of her dress
I was doing Mikes washing the other day and his Y-Fronts were completely covered in Bum Pepsi
That's the last time I felch Norris again, I ended up with Bum Pepsi running down my chin
