Fratricide 

Fratricide is when you kill your own brother.

Fratricide is when you kill a brother in arms (soldier or political/religous brother) who you are fighting with either on purpose or by accident.

Cain committed fratricide when he killed his own brother Abel in the Book of Genesis.

In 9/11 the terrorists not only committed mass murder but they had also committed acts of fratricide against their own Islamic brothers.

Fratricide 

That one Steam award you get when you kill the companion cube in Portal. You know, the one that made MatPat from Game Theory make a video about how the cubes have dead bodies in them.
(also, the actual definition is killing your brother/sister)

Jeff: You get to the part in Portal where you have to incinerate the companion cube?
Brian: Yeah. It's a shame. That cube was like a brother to me.
Jeff: Whatever fratricide is, I don't want any part in it.

Fartricide 

When forces unknown to human kind cause a person to expel a very potent fecal gas that is so overpowering not only do innocent bystanders have to vacate the area immediately or face certain death, but the CDC would classify this incident as a Public Health Emergency. The person that expelled this fecal gas is put in a near death state and will die if not removed from the scene.

"Hey did you hear about Mel? He committed Fartricide on Tuesday. They had to Hazmat the area and rush him to the ER!!"
