Bum Pepsi

The worst kind of liquid diahorrea

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

BUM HUNGER

When the subjects trousers / shorts are wedged firmly between their butt checks. This gives the illusion that the subjects bum is hungry and eating the subjects trousers.

Hey rob, take a look at her bum. Her bum is eating her trousers.

Yes, that is serious bum hunger.
