Guinness Book of World Records

The book which is actually just a website or it would have reached Mars by now, contains world records. Some of them are crazy, some are weird, some are crazy weird. But it's great to know that if I ever become the first person to eat eggs out of some sort of weird shit, my name gets put in an imaginary book to get me some fame.

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."
