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."
