Hi, Deadman and all.
Your search engine, believe it or not, is a very good thesaurus. At least DuckDuckGo and Google are. Try âslang term for [fill in the blank] if the thesaurus synonyms donât work for you.
Beyond my suggesting something like the âhappy trailâ for between the navel and the bikini line, or âbelow the bikini line,â etc if the area is there. If itâs actually someoneâs lap, try âfree parkingâ or âthe empty parking place.â
Cheers.
