Garcasm is a play on the word Sarcasm. It is used when replying in a
negative mannor. The word 'Garcasm' comes from
the words 'Good' and 'Sarcasm' = Garcasm. The letter 'g' can replace the letter at the beginning of any word to turn it
negative. For example:
Nathan: What do you call a man with
brown paper trousers?
Max: ???
Nathan: Russell
Max: Well that was a goke.
ie goke means
good joke, therefore telling Nathan that it was a shit joke, therefore was sarcasm, but as it was
not good sarcasm he sais garcasm.
Also this defines the word probs as Max could then say "that joke was probs funny"
