Jesus, thought everyone knew what a Tifo is, but just for you (obviously non footy fan people), let me explain.
Tifo is the word used to describe a colourful, vibrant and usually choreographed visual display by football supporters. It is also a phenomenon in other sports, such as cycling and auto racing.
Displays of a tifo normally occur within stadiums before and during games but can also take place outside a ground.
In many cases the visual displays are carefully planned and often each individual supporter forms part of a mosaic by wearing or holding a particular colour.
