Someone that is super rich, rolls in cash and has got everything you could think of... Spa rich is the downgrade of sauna rich... everyone has a spa but you gotta be sauna rich to have a sauna in your crib!
Sauna rich guy: Hey Baby... Whats your name? lets get out of here, somewhere a little quieter and cosy...
Girl next day to her girlfriends: Last night was wild... I met this guy he had everything, cars, pool, spa, sauna
other girls: damm sauna rich?
