slang for lower belly (under the belly button)?

Snail trail for men, referring to the hair that leads from the belly button down to the pubic area.

You should jerk off less, sleep more and be very blunt in the way you talk to girls but try not to turn into a dick. ex. a girl drops a pen bends to pick it up and you nonchalantly say "nice a*s" always works and girls like confidence which your "growth" problem prevents you from having.

I hate this slang phrase but I have heard that area referred to as the F.U.P.A. or "fat-upper-p**sy-area". Pretty vulgar and pretty popular phrase where I'm from. It's pronounced foopah, not as the acronym itself.
