Horsi Kari
The act of ritualistic suicide engaged in by an individual upon realising they are a fan of My Little Pony: Friendship is Magic. Similar to Seppuku, this ritualistic act is completed to atone for one's failure of good taste and decency.
"I've realised that I've spent the last six months of my life fantasising about miniature horses. I realise the burden this has brought upon my family and that the only way I can atone is with Horsi Kari."
