Loosely linked the the movie about
psychopaths and serial killers released in 1991, 'The Silence of the Chavs' is when a group of chavs usually led by an 'Alpha Chav' give you the chilling
silent treatment trying to shame you into their 'Chav' way of thinking
missing the point that you are not like them so are mostly or completely immune to the shaming which might seem oddly funny afterwards.
