It was originally a painting by the Famous painter NUB Frez but then evolved into this trend of phrases. The Phrase it usually used for people that sit at home surfing TV channels so fast that little coloured boxes appear out of it and finally the people get eaten by their own TV.
This concept is very well known in the nordic countries, for example Iceland.
There was also a band formed connected to this WolfTV idea and named after the painting. The music they play is electrosynthgladiatorbeat.
