McFuckup 

People who reside in Mcdonalds for most of their lives. They are nocturnal creatures who looks similar to the inside of a yaks arse. They have a distinct smell of rotten testacles with cheese on toast.

The boys John (fatus) Dalton, Patrick (retard) Quinn and Alistair (Poofter) Lobb are perfect demonstrations of the word McFuckup.
