What happens when, after a long hard ride on the Palm Express to Tissue Lane, your manhood randomly decides it just isn't finished yet. After a longer and more satisfying ham-spanking session, it is still not done. In fact it won't go away, no matter how long and hard you work at it. It is like a zombie, because it will not die. In fact -- it is a zomboner!
Dude, I jacked off nine times last night. Zomboner!
My zomboner is killing me man. In bed, in the shower ...
Jack: "What the fuck man, you've got a boner at football practice?"
Billy: "Zomboner, man!"
A posthumous erection caused by rapid or violent death such as a bullet wound or a traumatic blow to the head. Death erections can also be provoked by auto-erotic asphyxiation, (like in strangulation or hanging).
