I have personally tried a leaf, after comparing pictures on the internet, and am happy to conclude that I think my bush is of kadok.
On a separate note, I wish to extend my heartfelt apologies my esteemed AWHIFFOFLEMONGRASS took umbrage by my suggesting her people are a "sirih chewing species". It's as insensitive as concluding that all chinks have slitty eyes and use chopsticks. Anyway, we discussed the issue at great depth, and this was the snippet of our ahem, every D&M conversation:
Thamby: call my ppl "sireh chewing"
Me: arent they?
Me: its an honor
Me: time honored traditions are hard to find
Thamby: kiss my black A**!
Me: I would chew it if i knew how, and liked the taste
Thamby: my black A**?
Thamby: What what?
Me: what ack?
Thamby: you said u'd chew my black A**!
Thamby: YOU SAID "I would chew it if i knew how, and liked the taste"
Me: i did notttt
Me: chew sirih la donk
Ah, isnt heart warming to know this is what friends are for!!!! GUFFAW.....
