Red cock!
well anything is fine as far as the tone is respectful and/or not derogatory. on the contrary, in my experience, most people find 'tapai' derogatory:D. i am fine with hajur as far as it's not used as in..."lau na yeti gardinu paryo, hajurrrrrrrrrr" bowing 90 degrees in front of the so-called 'hajur' :D
