Sayoricide 

When your childhood friend commits the dead. Usually done after confessing to her that you either love her or will always be her dearest friend. And you can never change what happens.
Never.
Never.
Never..

I just witnessed a Sayoricide, must have been DDLC.

Snoricide 

The act of killing an extremely loud snoring person. This is usually done by nudging, pushing, kicking and loudly sighing the person to death.

"This is clearly a case of snoricide. He died as a result of futile efforts to get him to wake up and stop snoring. At times attempts to get him to wake up included kicking, poking, jumping on the bed and loudly sighing 'wake-up and stop snoring dammit!' to no avail. The outcome was inevitable."
