A complimetary phrase, if applied in a positive sense (chuf up), given by someone if they see someone else do something that is
funny/cool/really stupid.
Also an insult if applied in a negative sense (chuf down), if someone commits an act that is agreed by the surrounding
people to be gay/douchy/fagatronic.
Also a rating scale. By "chuffing up", you increase your chuf rating on a scale that ranges from -
6 to 6. If you have negative chuf,
like Gary Miskovsky or Oprah, you are a dick.
