I generally bite or tear my fingernails off and tear my toenails off with my talon-fingernails. I like to keep my nails long, not only for giving backskritches but also because if I cut them it feels like I'm missing the top digit of each finger and I can't use my hands for a couple days.
Don't hate the act of cutting, though. Just never remembered to do it, and now like having claws.
