The WAI - Traditional Thai Greeting
WAIWAI is used to call interesting, exciting, and a little strange or unusual things that make people go "really ? wow !"
WAI! - This is an exclamation that is used a lot in Japanese. It's like saying "Yeah!" or "Yay!". They use it a lot when they're really happy.
WAI is used also for:
3) Good Bye
5) Praying to the Buddha
The "WAI" is really a sociable thing, invested with fine cultural nuances.
The person who usually gives the first WAI is the one showing the respect to the other person.
In your example:
- "are you available?"
- "wai wai." = Yeah! Yay!
