When a female gives you rough oral sex and you wake up in the morning to find that your penis has marks or bruises on it.
This word is a combination of "blow" and "owned".
I was with this girl from work last night. We both got pretty drunk, we started making out, and then she went down on me. It was one of the most painful blowjobs ever. Teeth, too rough, etc. Now this morning I woke up and checked out my pen0r and its like black and blue around the tip, badly bruised.
You got blowned.
