look up any word, like thot:
1) A swear, should not be said inside, or near, a church. Is is basically the single worst insult kinown to man. Imagine someone who is unfit to be even considered an ass hat. This is a Kylor.

2) A serious sexually transmitted disease, the result of interspecies homosexuality.
Person 1 : "You stupid, fuckwit, cunt face, motherfucking, shitdicking, kylor"
Person 2 : "Kylor? you go too far man..."

Patient : "Give it to me straight doc"
Doctor : "Im afraid you have Kylor. Now get the fuck out of my office you filthy piece of dickchease, go walk in front of a bus."
