RCS, Rumpled Crotch Syndrome

The social faux pas (similar to vpl on a lady) for a gentleman or Sloane Ranger to wear trousers which are two large resulting in creases and suspicious-looking cloth bulges in the groin area.

Sadly, however, the Prime Minister's trousers were too big; he was suffering from RCS, rumpled crotch syndrome, which afflicted the previous Tory prime minister.
