Bongs
From ASSS Wiki
Bongs are sounds that can be played with messages. A bong can be sent with a message by placing the bong number preceeded by a '%' anywhere in the message. The bong number is removed from the text by the client and then sent in a special field in the message packet, so the number will not appear in the message once it is sent.
Here are the messages and their numbers:
1 = Beep, type 1 2 = Beep, type 2 3 = You're not dealing with AT&T 4 = Due to some violent content, parental discretion is advised 5 = Hallellula 6 = Ronald Reagan 7 = Inconceivable 8 = Winston Churchill 9 = Listen to me, you pebble farting snot licker 10 = Crying 11 = Burp 12 = Girl 13 = Scream 14 = Fart1 15 = Fart2 16 = Phone ring 17 = The world is under attack at this very moment 18 = Gibberish 19 = Ooooo 20 = Geeee 21 = Ohhhh 22 = Awwww 23 = This game sucks 24 = Sheep 25 = I can't log in! 26 = Beep, type 3 (same as priv message alarm sound) 100= Start music playing 101= Stop music 102= Play music for 1 iteration then stop 103= Victory bell 104= Goal!
