obchaste
A person too fat to get it on, stuck in a loveless, lustless, lifeless loop of no sex and pure shame.
My cousin's been obchaste for a year. He’s too big to fit in the bed and too sad to try.
She broke up with him because he couldn’t even get it up. Now he’s just obchaste.
He tried to text her. It was just a selfie and a ‘I miss you, but I’m too fat to do anything about it.’
