maybe he is jus trying to say hi in a rough way...some people are born with a rough face...there was once me an Eskar(another white r33) was on our way for karting and this r33 guy overtook us, I told Eskar before he passed us "yea, another r33 guy that gonna say hi," and when he stopped next to us..the first thing we wanted to do is to slap his face...
