when someone's dead for a while and their limbs stiffen (not the penis, though if the corpse is laid face down, the flow of blood to the penis can result in an erection.. a treat for necrophiliacs)

Rigor Mortis happens about 3-6 hours after death. It starts in the head, and goes down to the feet. It begins to leave through the feet and exits through the head. This has nothing to do with blood. That is post mortem lividty. Rigor mortis occurs as a result of a chemical change in the muscles of the decedent, causing them to become very stiff and difficult to manipulate.

Also, this has nothing to do with erections that is called a "priapism".

Something that is very stiff and hard to move.

the stiffening of joints after death, or a stoners last respects to a dead bong-buddy, in other words lighting up to honor the dead

use this word to describe your penis when its erect.

A Texas metal band that came along just after Boss Tweed and Pantera and was signed on Capitol records. Rigor Mortis was best known for songs like Speed Whore, Mummified and ZOG. They were also well known for being heroin addicts but still a top notch very professional band. One night at Joes Garage while Rigor Mortis was playing a guy jumped up on the stage and stabbed a couple of the band members.
