On the evening of January 25, 2001, the conversation in the channel was revolving (again) around 4:20 with various people remarking how it was "time to stuff a bowl..." AL2001 remarked that "it's time to stuff a cock in my ass" Since this happened at 9:25 pm, Nutation was inspired to come up with 9:25, aka "stuff a big dick up my ass time." It doesn't really mean anything, but Nutation thinks it's a funny thing to say.
