My understanding is when a male says Khrab Phom, it cam frome the old, old days when you would use this to someone of higer status, basically saying your hair/head is lower than low, that you would permit them to walk on your hair/head. I think it is a hyper-humble, obsequieous phrase. I read about this a long time ago and angry that I can;t remember it verbatim >

Well, that's Gra Phom ¡ÃмÁ, which is an older form of ¼Á, more polite as well. It is different from Krap Phom ¤ÃѺ¼Á

Krap Phom is very similar to Yes Sir, or Yes M'am.

And you can also end up with a highly polite, but probably high-brow sounding ¢ÍÃѺ¡ÃмÁ Kor Rap Gra Phom
