In the majority of male toilets of the University of Newcastle, a genre/style of graffiti has emerged and spread all over campus.

Written in the grout, between the tiles, is a huge web of witty one-liners (and no-brainers), all based around the word grout .

Some examples: Alexander the Grout

Grout Wall of China

Grout tits

I'm the groutest

The Grout Gatsby

And so on.

Some people have too much time on their hands.
