OXmas 

Christmas in Oxford. As the Oxford academic term finishes around the first of December, the OXmas season is approximately a month earlier than Christmas, but shares all the same festivities and traditions.

Merry OXmas!

Omashu 

(n.) the second largest city in the Earth Kingdom (second only to Ba Sing Se), one of the last great strongholds of the Earth Kingdom during the Hundred Year War.

(v.) to steal, usually in a manner that is very unexpected or surprisingly (often without fighting); to conquer, usually in a comedic manner. Note: the act of omashu-ing is often accidental and unintended by the do-er. This is often accompanied by lots of confusion, especially by the do-er, and potential laughter (most commonly in recollections of the fact and from outside viewers).

(Most often done by Zuko in MuffinLance's stories on ArchiveOfOurOwn.)

Zuko omashu-ed Omashu by challenging Aang to an Agni Kai-- upon his victory, the Fire Nation gained control of Omashu.

Mike Oxmall/Mike Oxlong 

These names are plays on words to get gullible folks to say "My Cock's Small" or "My Cock's Long." Either one works on a fool.
*Mike Oxmall can also be spelled "Mike Oxsmall for more subtlety.

Chad: Oi mate, I changed my name to Mike Oxmall.
Bradley: Hi, Mike Oxmall.
Chad: You muppet.
Bradley: What?
Chad: Mike Oxmall/Mike Oxlong

Oumasai 

Oumasai, also known as saiouma, omasai or saioma, is a ship involving Kokichi Ouma, the Ultimate Supreme Leader, and Shuichi Saihara, the Ultimate Detective. These two are characters from the third killing game in the Danganronpa series, Danganronpa V3: Killing Harmony. They are not toxic, like most people make them out to be, and should not be portrayed as abusive or creepy. However, they do have an unusual relationship, as Kokichi is a very unusual person. This ship is supported by a lot of the fandom, although some people prefer to ship Shuichi with Kaede Akamatsu or Kiibo.

Someone: Saimatsu is such a good ship!
Me: It is, but I prefer Oumasai.
Someone: Oumasai is valid, but I don't really like Kokichi.
Me: *le gasp* why? He's best boy!
Someone: He's a rat :(
Me: Its okay, your opinions are valid, but Kokichi is my favourite.
Someone: That's fine :)

oumasai 

Oumasai is the ship name for the characters Kokichi Ouma and Shuichi Saihara from the visual novel New Dangan Ronpa v3: Killing Harmony (or 'everyone's new semester of killing' in the Japanese version). It ship so amazing and cute it makes me want to rip out my own eyeballs.

But sometimes people like to fuck it up and make it seem abusive and disgusting which is NOT OKAY.

Person 1: {Kiibouma} is DEFINITELY the best ship involving Ouma

Person 2: Are you kidding me?. Oumasai is where it is at

Omastar 

Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.

Before its own heavy shell led to its extinction, Omastar swam the seas in search of prey. Even the hard shells of prehistoric Shellder stood no match to Omastar's deadly powerful bite, and were quickly made a meal of by having their insides sucked out.
