I gently open the door is a "joke" from the game Doki Doki Literature Club. This was made into a meme of the text "I gently open the door" displayed and an image of dabbing hanging Sayori.
A really hateful and racist term for a white girl who wants a interracial relationship. It says white women are nasty, smell bad, and always take a dump with the door open.
She's beautiful and sweet, but I don't want a 'doodoo with the door open.'
