A Vladimir
When you grab your dong and start jacking off like you're trying to beat the world record before you pass out. Can happen anytime, not just when you're tired.
Bro, I did a Vladimir at 3 a. m. and now I'm falling asleep like a baby.
I did a Vladimir before my mom woke up. She didn’t even know I was up.
I did a Vladimir in the shower and got soap in my mouth. Classic.
