Abbreviated informal British slang, widely used in the South East (extending beyond London) meaning 'bum/ arse/behind' etc.
The word is often said as 'harris' by people who have only heard it spoken and have no idea where it comes from.
Get off your fat Aris and do some work!
Ye gawds my Aris hurts.
