a line in the song "Pigs", from the Pink Floyd album {Animals. The band is making fun at British politicians, although the sentiments can be applied just about anywhere.
You bus stop ratbag. Ha Ha, Charade you are!
You fucked up old hag! Ha Ha, Charade you are!
... hand over heart ... I'd say you're a laugh ...
but you're really a cryyyyyy-iii-iiiiyyyyyyyyyyy
The most beautiful person you’ll ever see in this fucking world. She will marry Yuyu and only Yuyu and she’s the most amazing and beautiful person you’ll ever see. It’s like she’s sent from heaven itself.
British phrase coined by Pink Floyd in the song Pigs (Three Different Ones). The phrase implies that you are being use'd especially in the form of higher power (I.E the government). In book Animal Farm the pigs are the Government and the dogs are the police, this also supports the meaning of the phrase because as quoted from the song dogs:"Gotta admit, that I'm a little bit confused/Sometimes it seems to me, as if I'm just being used".
