I remember seeing the true story of that picture awhile ago. The woman who created that image was some kind of graphic designer I believe, from a certain European nation (bare with me I vaguely rember the exact details and don’t care to refresh my memory on the subject). While the meme man is fake she did base it off her then boyfriend who was not muscular at all, although still a moderately handsome dude. She created the “giga chad” as some kind of art project and used the boyfriend as the base model and exaggerated all his features to a ridiculous level. Posted it online and the picture took on a life of its own.
