Gruff Nuts

Gruff Nuts are the little balls of poo that find themselves entangled with your bum fuzz.
Gruff Nuts are similar to dingle berries, the difference being that Gruff Nuts get that tied up in your bum hair that to pick them free means ripping out a good patch of arse lawn.

My house mate was screaming in pain this morning picking out all his gruff Nuts.

A very large tubby kitty, sometimes referred to as “G” for good measure. Will also beg for treats.
