When I was in school (a few years after I graduated), we had one jamshut instead of a cleaner. So, one day, some idiot wrote on the wall with a black paint. Jamsut was instructed to paint this unnecessity, since the wall was yellow, he mixed the yellow paint and painted it right above the black. The inscription remained, but instead of black color broke dark orange. The director glanced and ordered to paint the whole wall with another paint, but we had a green wall in the yellow corridor:) with the "h*em" again standing out, this time because of the collage of layers of paint, clearly so burgers pass, close to disassemble the eye is easy. The director was angry and said to cut off this "x*it". The next day we had a green wall in the yellow corridor with a brick-shaped inscription "X*Y".
Since then, this wall has been named "Our Rasha"
