It came from a 4chan reply where the Original Poster (OP) was responding to someone asking him why he was never been this horny for Galactus before. The thread was initially about buffs and nerfs for a new season of Marvel Rivals and can be found here with an image of the meme here.
Listen here fucker.
I have been jerking off exclusively to size content since I was 11. Twice a day, every day, for the past 16 years, I have scoured the internet for every single piece of Giantess, Shrinking, Macrophilia, every fetish and subfetish contained within. All of it.
There was a point up until the pandemic in 2020 when I literally had seen and read every single piece of content concerning big women.
Don't you fucking sit there and tell me "you've never been this horny for Galactus" before you piece of shit. Her name is GALACTA, and YES, I have known about her. I have always known about her. She was my most niche waifu, my prized possession. There were EXACTLY SIX PIECES OF FANART dedicated to this character prior to 2024.
Now she is a global phenomenon. I could not be more proud or happy. However I will fucking kill you if you try and tell me I'm some Johnny-cum-lately who just hopped on the band wagon.
