When you get a boner so hard that you die.
Man! Lauren was so hot that day and my boner was so hard! That I had a seizure and died. It was an epic death by boner bro.....I'm a ghost by the way teehe!

Get the death by boner mug.
The act of having an erection post-mortem, usually caused by hanging or some form of asphyxiation, also it is know to be the biggest, hardest boner one will experience in their lifetime (or death as the case may be).
Man, I saw Adelinas' ass in a bikini, that shit gave me the death boner!!
