Lets begin:

1. Go to the android market. Search for "AndChat". Andchat is 100% free.
2. Download AndChat. Shouldn't take too long.
3. Open AndChat.
4. When at the homescreen, Your going to want to press your Menu button. Then hit New Server.
Your going to be shown this screen.

At this screen, type in this information:
Server Name: "Toribash-IRC"
Server Address: "irc.toribash.com:6667"
SSL? : Don't check this
Nick 1-3: Enter whatever it doesn't matter.
Username: Desired name.
Autojoin: This is the channel you will join once it connects to the server. For example, you put "#support" .
The rest: Leave blank, unless you want something in there.

Now, Once your in the server. As well as joined your channel. Your name might be "AndChat([Username]@***********.***).
Type /nick desired name to change your name. For example "/nick May0" would make my name "May0".
To join another channel type "/j #channelname". Ex, "/j #toribash".
You can also press Menu to change a bunch of settings, like default username and other names if your default is taken. As well as getting a notification if your name is highlighted.
