📜 Oshirimpics 2025: Official Regulations
🍑 The butt must be the main focus.
Submissions where the butt is the star of the image are encouraged — more so than the face or full body.
🚫 No anus exposure allowed.
This is considered a violation equivalent to doping. Any such submission will be instantly disqualified.
🛠️ Excessive editing or AI-generated images are prohibited.
We value realness. If you're a man, show up with nothing but your own body!
🔞 Entrants must be 18 or older.
Sorry, kids — come back when you're grown.
I'll be waiting for you... up here.
🧑🎨 Keep it classy (kinda).
Stay within the bounds of public decency. Artistic, humorous, or cheeky submissions are welcome!
