Onder

To overtly use proper grammar, really long sentences, and pompishness in day to day life.

Brian: "Hey dude let's smoke a blunt"

Onder: "I do think that is such a terrible idea, and thus, we should not do such a thing. But should you wish to do so, you do understand that you would be breaking the law and have a chance of being imprisoned? I beseech you to not smoke such cannabis in my face"

Brian: "wtf dude why are you so onder?"

Onder: "I am deeply offended at your usage of such profane language. Please abstain from asking me with such brash and terrible manner."

To pull an Önder on someone.
He pulled a Önder on me!
Don't you dare to pull an Önder on me!

aka Ruel van Dijk, the sweetest human bean to ever walk this earth. Also quite tall. Looks cute in bucket hats and literally anything else. Can be spotted dancing awkwardly, yet adorably, at any time or place. Or saying, "AreeeeeeeeeEeeeeE YOU REaaaaaaaaaAaAaAaaaaaal", as it is his famous catchphrase.

We love lanky boi oneruel.

ODer

An ODer is short for Online Dater, which means two people are dating in online games, media, etc. without knowing them in real life. ODers are most mentioned in Roblox a lot, and sometimes people even troll ODers while recording, to put it on Youtube. ODers get called out a lot, becuase you actually never know who you date, then the ODer will start running away, ragequit, or get defensive, which the ODer hater will win a lot.

"iiOmqBlazin: Hey, you single?"
"iiOmqItz_Kyli: Yeah."
"iiOmqBlazin: Wanna d8?"
"iiOmqItz_Kyli: <3"
10 Minutes Later...
iiOmqBlazin and iOmqItz_Kyli getting it on in a virtual game. (smh)
ODer hater walks in.
"Areomy: wtf you kids doing your like 11 you have to date on a virtual game cause you can't get someone irl."
"iiOmqBlazin: shut up freaking ###### ### ###### no one likes you noob"
"Areomy: no wonder why you're adopted."
*iiOmqBlazin has left the Server.*
*iiOmqItz_Kyli has left the Server.*

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.
