Octopubes 

Octopubes occur when you attempt to wash your pubes in the shower by getting them soapy and pulling them out to the sides. This causes them to combine into thick strands resembling octopus tentacles.

"When I was in the shower today, I went to wash my pubes and by the time I finished I had wicked Octopubes"

Kate's octopus defense kicked in when we were hooking up at that party. She inked all over the place, left me seeing red.
