My girl usually say something like 'pee kha' to get attention of waitresses, taxi's etc, I thought she was saying 'yee ha'. So I started using it to get peoples attention, then wondering why they were laffing at me. Apparently ive been going round telling coach drivers and shop owners to 'f*** off!'
Would be a female trying to get the attention of a person believed to be older than her.
Perhaps you could try, "Kor toat Krap!" or "Nong Krap!", assuming you're a bloke and the folk your trying to get the attention of are younger than you.
