cactipuss

A woman's vagina after not having been shaved for a short period of time. Essentially, a vaginal five o'clock shadow.

-Hey dude, what happened to your face? It looks like you have a rash or something gnarly.

-Na, it's from that girl last night. She looked clean downstairs, but upon further inspection, I was surprised by a cactipuss.

-Damn, don't girls know how to keep it clean any more? What is the world coming to?
