My  fat dyslexic fingers try to make six calls hopefully before the enemy has aquired the six of a teammate.
It goes something like this  "FEunkeds 6665"
That is usually followed by "sheesh guys thanks for the six call" To which i want to reply that i did call out  6 but it was jibberish.  

Now RW is much more effective,  for instance I can be in the bathroom when I hear "Dogftr 6" And I can run to my computer with my pants around my ankles to give my old  microsoft stick a stir.  
 Heres a favorite of mine.
Pilot#1:Yap yap yada yada yada  yap yap 
Dogftr: pilot1 66776!
Pilot#1: Yap yap yada yada yada  yap yap 
Dogftr: pIlot1 666666666666666
     KABOOM!
Kill of Pilot#1: by Inopportunist of The typing death squad.
Pilot#1: whoopee Knights! Never any six calls!.
Pilot#1: Yap yap yada yada yada  yap yap
