I have the beginnings of a salt-and-pepper beard. Can I be an old fart too?

If I can't slag Spaw any more, I will have to regretfully leave the 'Cat. Slagging Spaw is what gives my wretched, pitiful life meaning. Slagging Spaw is more fun than a barrel full of monkeys with Ebola Zaire (actually just about ANYTHING is more fun than a barrel full of monkeys with Ebola Zaire). Slagging Spaw puts the sun in my day.

What does "slag" mean, by the way?
