Ore-Sama 俺様

ore-sama 俺様 is the over-the-top combination of the first person pronoun, ore-sama means the same thing as ore, "I," "me," in English, except it's ridiculously pompous and people would only use it in real life as a joke.

Which means it's mostly a trope used in manga and anime. (just like

Manga: School Rumble

• ore-sama ni
  fukujuu se yo.
  俺様に　服従せよ。
• Submit to me.
• I command thee to submit to THE GREAT ME.
• e... え…
  Eh...

Characters use ore-sama to imply they're extremely important. It's used by the type of character that would say "I'm the strongest" or "the smartest" or "the bestest" or stuff like that.

Manga: Zatch Bell! / Konjiki no Gasshu!! 金色のガッシュ!!

• yakamashii'!!! やかましいっ！！！
• [You're] "noisy"!!! (literary.)
• [Stop annoying me!!!]
• ore-sama ga, nande
  an'na tei-reberu na
  yatsura to tomodachi ni
  nan'nakya
  ikeneendayo'!!?
  オレ様が、なんで　あんな低レベルな　奴らと友達に　なんなきゃ　いけねーんだよっ！！？
  Why do I have to become friends with low-level guys like those!!?

That doesn't mean it's true, though, it just means that's what they think about themselves.

Manga: Dragon Ball

• ko' kono ore-sama ga
  taishita koto
  nai dato......!!!!
  こっ　この　オレさまが　たいしたこと　ないだと……！！！！
  Th-- this me isn't [a big deal], [you] say......!!!!
• sou da
  そうだ
  [That's right.]
• ima no kougeki de
  wakatta
  いまの攻撃で　わかった
  With [that] attack [just] now [I] realized.
  (Goku figured Nappa isn't a big deal from how weak his attack was.)
