Intentional phonetic spelling of "Oh my god". If said, it would be fast and all one word "like, ohmigod!" The word prefix 'like' is often placed in front of it. The phrase is used mostly by pre-teen and teenage girls and should in no way be a means of deducing the person's I.Q. - but it pretty much speaks for itself anyway.
Like, ohmigod, I totally dreamed that Matt Damon was kissing me!
Ohmigod, no way!
1)(N). A japanese butthead who likes to hide inside his house, who never turns the lights on cuz it 'costs way too much'. Has stupid little eyes and a big flat nose and only pays $1 donations that are meant for 100 workers, yet is the president of a company. Ochigawa says that its another issue. But we don't know...
2)(N). A (preferabbly japanese) recluse.
No hard feelings, buddy.

"That's another issue." Said Ochigawa.
Stop being such an Ochigawa.
