NetHirc is a bad pun and a Net::IRC client. It is terminal-based, and it comes with many silly Nethack-inspired messages. NetHirc is very modular and extensible; if you know Perl, you can customize NetHirc, and reload your changes while it's running. If you don't know Perl, you can still customize all the messages and mold the client to look like you want it. If you've become frustrated with other IRC clients that have nasty scripting languages and take themselves too seriously, then NetHirc could be your ticket to enjoying IRC again.
