I study rainbows
Someone who says they study rainbows is probably a boy who thinks he's a teacher of gayness and uses stupid words to sound smart. They know all about genders and think they're the best at it.
My brother said he studies rainbows and thinks he's the best teacher of being gay.
She said in a tweet, 'I study rainbows and I know you're just a student.'
He posted on Instagram, 'I study rainbows and I know all the secrets.'
