A while ago on the dark web, you found a mod that has nothing in the description but you download the mod anyway. When you download the mod, nothing happens so you decide it's just a fluke so you go alone with your day until you walk into the door and see Girlfriend as a giant blob of squishy softness of fat.

Girlfriend: BOYFRIEND! WHY AM I FAT?! DID YOU HAVE SOMETHING TO DO WITH THIS?!
