Well, ever since I ditched HackThisSite (Being lead developer, with no devs, wtf?) I haven't had much to do. Computers sorta bore me now, it's been nearly 10 years since I started on DOS.

It's a basic DOS (Denial of Service) attack, I used it on IRC servers. Ironically, that was also back when I was on hackthissite (2005-2009.)
EDIT: I have a C version somewhere, that's way faster. Lemme see if I can find it.
