The pubic hair left in the bathroom after one shaves or trims for the first time in awhile. No matter how much you try and clean them up, they never leave.
"Common John! your after pubes are all over the counter...and the shower!"
"Oh shit, my after pubes are everywhere, I shouldn't shave in my parents bathroom anymore."
"Next time, I'm gonna trim my pubes outside. These after pubes in my bathroom are so annoying."
