Clitty litter can be white, red, green, or even brown. This depends on the recent activity of the woman, and her attention to personal hygiene. Check the woman's panties for skid marks!
Example two: My girlfriend just got out of the shower, so there was little chance of encountering any nasty clitty litter.
Becky: OMG, I totally had a clitty litter episode last night!
Katie: Like wow! We are so like, clitty litter buddies!!
