Nonce

Derogatory term for a sex offender in prison. Now a general term for a prisoner on the vulnerable prisoner wing. Contrary to other definitions, the actual origins of Nonce are: Not Of Normal Criminal Element. This was because in times past, prisoners (whether sex offenders or not) were not "Normal" for whatever reason. Recently, the phrase has bastardised into just referring to sex offenders.
I see that pervert's on the nonce wing.

That nonce needs his bollocks chopping off

To be sentenced to a term of imprisonment.
Bob was weighed off with a ten stretch.
