A rhetorical question, generally in the form of an insulting chant, accompanied by finger-pointing; meant as abuse to a single person or team performing in front of a crowd, by indicating that they are unknown and insignificant.

Abuse is aimed at two groups:
1) An unknown competitor, whose relative anonymity is highlighted even further.
2) Paradoxically, a well-known competitor whose high credibility and status is undermined in an act of defiance by pretending to regard the competitor as unknown or insignificant.

Abuse is aimed in two ways:
1) When the competitor is announced.
2) When the competitor is performing badly.

The phrase is often used in sport, particularly at football matches in the UK.
