Guinness 

A potentially extinct term which roughly translates as 'copycat'. Origin and etymology is uncertain, but late UK Gen X-ers may remember the castigating call of 'Guinness!' in school classrooms when one pupil copied the idea, work, or joke of another.

"Tommy's such a Guinness - I saw his homework and he's copied all of my ideas! I'm gonna to tell on him."
