shook <on-type> <args>
SHOOK throws an event for the /on type you specify. You must be careful when throwing an event for an on normally thrown by a server message that provides a $userhost() value, because that $userhost() value won't be provided, and the /on may get confused.
To fake ON MSG:
/shook msg Me This message is fake
