Whilst I'm in agreeance for most, I think that 'dude' should also filter to 'mate'.
'Bro' to 'LOL UM FRUM NEW ZEELUND!' or similar,
'Chap/lad' to something about britfags.Perhaps 'Fritzel' to 'schnitzel'?
Also, I disagree with filtering 'lady'. Sheila GaGa. Enough said.
Also, 'Dingo' should be 'Pauline Hanson'.
Eg, "Pauline Hanson ate my baby!"
Please take my thoughts into consideration :)
