The act of leaving a gift behind after a night of sex to make up for any lack of contact until the next time you're horny. This gift normally consists of a log of shit on her pillow. When discovered, it will cause the recipient to exclaim, "Oh James..." Just like a Bond movie!
"Wow, you aren't going to call that slut you picked up last night? How are you gonna bang her again when you're desperate?" "No worries, I left an Oh James on her pillow, she'll love me forever."
