a lesbian who has never done anything with a man (gold star), plus they were born by artificial insemination, so at the time that sperm met egg, there was no penis present.
Girl 1 - I hate those girls who have made out with guys before but say that they're lesbians... I'm a real lesbian, I've only been with girls.
Girl 2 - Yep, you're a gold star lesbian!
Girl 3 - Actually, I'm a platinum lesbian... there was no dick at conception.

Get the platinum lesbian mug.
a platinum star lesbian is the opposite of a platinum star gay. this means a lesbian who has never slept with a man and was born via vaginal birth, meaning the first thing they ever did was touch a vagina.
“hey isn’t that girl a gold star lesbian?”

“no. she hasn’t slept with a man, but she was also born vaginally. she’s a platinum star lesbian.”
