When one attacks oneself verbally during a period of sadness or other negative emotion (anger, etc.), usually with plenty of force. (Ex.: Calling oneself an idiot, retard or other attribute that insults the person’s intelligence, actions, etc.). One will frequently speak in 2nd person. Sadness Aneurysms come in 3 stages:

1. The victim will begin to feel their sadness change to anger, and will occasionally begin to growl, grumble or otherwise voice their emotional morphing.

2. The victim will begin to mentally insult themselves, yelling insults at themselves in their heads. You should be able to tell by now if they are having a sadness aneurysm, as their face will frequently turn red.

3. The insults become verbal, and the person may mumble or shout them, depending on the severity of the sadness aneurysm. Eventually, the person will either cool down, or commit mass homicide to all around them. It is best not to talk to them, particularly in this stage, as they may lash out, making the sadness aneurysm worse. This stage gives the sadness aneurysm its name, as the victim will usually act as if they are having an aneurysm.
John: Dammit! You should have gotten that test question right, you bumbling, idiotic fool! How can you live with yourself?!

Steve: What’s up with John?

Tom: Leave him be. He’s having a sadness aneurysm because he messed up on an easy question that failed him the math test today.

Steve: Oh. Ok.

A masturbatory technique wherein one gets into the shower, turns the hot water on as high as can be withstood, then proceeds to squat down and masturbate furiously. Upon reaching orgasm, stand up and turn the cold water on full blast. If timed right, orgasm will occur at the same moment that icy water pours over you, causing an experience unlike anything you've ever felt before.
Dude, I gave myself a brain aneurysm right before leaving for work, it was intense!

Similar to a seizure, but begins at the hands/fingers and rapidly works up to the rest of the body. Wrist aneurysms are undetectable, but can be triggered by the victim. The victim will lose control of their body. One of the many symptoms of Ratpiss Disease.
