Yup, I know what your saying, XCNuse.  A simple Hi is sufficient, really no matter what language is native to you.  Almost everyone can speak/type English.  And the LoooOOOoooZZZZZ!!!!1111!!!11 drives me crazy.  And also, just simply say sorry.  No need to have a freakin comical sentence binded.
 
Me, I have 4 buttons binded to chat, Hi, :-), Sorry, and good race.  Sometimes I change good race to no problem or good pass.  Fkeys I have /w wr, /w pb, and I use to use this on the demo - Caution exiting pit road, racers coming.  Even though they would still run out between first and second place taking out the guy in second.
