ondore 

1. The character Marquis Halim Ondore IV in the video game Final Fantasy XII. He spread several falsehoods in the game, prompting a party member to exclaim, "Don't believe Ondore's lies!" Soon 4chan's /v/ discovered that Ondore in fact tells nothing BUT lies.

2. Has come to mean any liar in general.

Whether encountering "the" Ondore or any random ondore: DO NOT BELIEVE HIS LIES.

I think I'm going to buy that Phoenix Wright game. Ondore said it was terrible, so it must be great.

My girlfriend says she's not cheating on me, but she's something of an ondore, so I don't believe her.

onovirus 

When your band mate’s girlfriend breaks up the band.

The Beetles were patient zero of the onovirus when Yoko Ono convinced John Lennon he deserved more credit than Ringo, George, and especially Paul.

Ondoy 

A motherfucking typhoon that destroys and ruins everything and everyone.

Poured down the rain equivalent of a month, in SIX FUCKING HOURS.

Made floods as shitass high as your house, and left everyone standing on their roof, while waiting hopelessly for rescuers to 'save' them.

Guy 1: Did you go swimming today?
Guy 2: YES. I SWAM IN A 6 FOOT POOL CALLED FLOOD. FUCKING ONDOY.

Ondol 

The traditional floor heating system in Korea. Gravel or water-pipiping beneath the stone board floor. The fire in the kitchen can be used for both cooking and heating up the floor. Heat energy gets trapped under the floor that it can warm up the room with very little amount of fuel.

Ondol is an ancient technology, yet it still remains as the most energy-effective heating system in the winter time.
