It's fun, everyone I've met while doing that ends up confused.
If you want to try, here is the handbook for the emote language!
:3 = Happy, Hello, Pleased.
:P = Joking, lol, wtf.
>:F = Hard
>:| = Serious
:/ = Not sure, confused
:o = wat
:O = Suprised
>:O = Angry
Numbers:
1:! = 1
2:! = 2
3:! = 3
4:! = 4
5:! = 5
6:! = 6
7:! = 7
8:! = 8
9:! = 9
0:! = 0
1:0:! = 10
Do you get how it works?
You can also add a question mark at the end to ask if the person is that emote, and you can use the Windows character map to make up new emotes.
It's fun, we should all go on there at once and start annoying them >:3
