There are seven ratings on the normal joss-o-meter which are:
classendary - for the most amazing events
bloody brilliant - for that which seems classendary at the time yet wears off with age
classic - frequently remenissed over events such as "the bundle incident"
legendary - mostly reserved for people you would go to the pub with
average - that which is not worth rating
crap - events which are hyped and turn out to be below par
a bit shit - the worst people and things on the planet, such as George W Bush, Liberal Democrats, the Holocaust and rape.
"Wow, I would rate that party last night as classic on the joss-o-meter."
