look up anything, like your first name:
1. pughy
a large person you would name ben, they would have to be loud, annoying, and not give a shit about anything
oh my god he's sucha pughy
2. Pughy
n. A particularly smelly turd. Origin possibly from the sound "Pewee".

Alternatively it could be a reference to a much hated council candidate in the UK Midlands council elections who was renowned for very poor personal hygiene and even poorer personal morals.

"I would give it a minute or two before you go in there, I dropped a Pughy"
