'horrible person admitting' is the definition.
I know nothing about this answer so I cannot tell whether this works.

'prince is a nerd' is the wordplay.
I cannot really understand how this works, but
'prince' could be 'p' (abbreviation) and 'p' is found within the answer.

This explanation may well be incorrect...
