Lol I thought this for years! I always thought it was a bold choice for a bumper sticker. I was like "Ya! You do you!"
To be honest idk what they mean by salt life. Slut life I could wrap my head around. But salt? Do they harbor ambitions to become deckhands?
I really thought it was "slut life" for years until I thought, "Surely not this many people right?". So I searched online for slut life sticker and that's when I learned it was salt and not slut.
