What is Trapped Pube?
1.
Really uncomfortable situation in which a pubic hair beomes somehow entangles with another pube or with your underwear. Difficult situation in public places as it can be excrutiating, with the only cure being some personal hand to crotch contact - inside your pants.
I don't need an example - it has happened to most of us who have transcended puberty and not removed all their pubes by shaving or waxing.
