Onegg 

A person who drinks sixty gallons of coca cola, 5 kilogram of candy, yet has the metabolism of a hairy gorilla running across the country every day. He has the Intelligence of an illiterate panda in the african zoo, and becomes mentally ill after consuming sugar. Never does his homework yet does really well in school. Sometimes you wonder how he even is alive

John:"Hey look its Onegg!"

Onegg sprints towards john with a wild and mad look in his eyes. His gait is like a diabetic hippopotamus and his eyes has rolled over the sockets. Sticking his tongue out, he lets out a sickening and drunken laugh.
John:"oh no guys run!"

yoroshiku onegai shimasu 

Basically, this is said as an entry-level phrase to someone you have a favorable impression with, or if you are a very 'traditional' person. Another situation you would use this, is if you were being convinced to accept someone's hospitality. I am unfamiliar with the direct transliteration, but if you wash the grammar properly it comes out to be 'Please treat me kindly' or 'Please take care of me' or 'I am in your care, kindly' something to that effect. As you can see, this phrase is a trade of trust, where you 'ask' for trust, and 'give' trust by 'placing' yourself in someone's care.

Source? My frequent visits to Japan, and familiarity with its culture.

'Yoroshiku onegai shimasu, senpai.'

- Here, an underclassman at school or work who might have previously met this person they refer to as 'senpai' (or senior, upperclassman) Implores them to continue their goodwill now, and in the future. The meeting may be in front of the senior's friends, so the person wants to be respectful so their senior doesn't lose face.

Onegina Syndrome

A debilitating disease in which a man chooses to only see one vagina for the rest of his life (see: marriage).

The onset of Onegina Syndrome comes on slowly at first, initially affecting masculine activities with the subject's friends (ie. sports, vids, bar hopping, trips to vegas, etc). Soon the disease will accelerate and spread to all other aspects of his life, and the subject's identity begins to be transformed from that of an individual into that of a couple (see: siamese twin). Soon the subject is unable/unwilling to attend any event without his other half, and will make all social decisions based upon what will be best for his relationship. By the time Stage V Onegina Syndrome is reached, it's best to say goodbye to the individual and hope for the best. A manageable quality of life for individuals afflicted with Stage V Onegina Syndrome is possible, due to the hypnotic effect the disease has on the brain. The subject will often feel that their life is "better" or "more mature" now that Stage V Onegina Syndrome has taken hold. The friends of the subject are often the true victims of this awful disease.

Onegina Syndrome can affect anyone, especially if the subject is a nester at heart. You should not attempt to engage in masculine activities if you're suffering from OGS. If you're unsure if you're mentally healthy enough for masculine activities its best to first consult your gynecologist.

Guy 1- Hey guys, I'm ordering the fight tonight! Lets hit the strip afterward and do it up!

Onegina Syndrome Sufferer - I can't man, I think Lacey and I are just going to pick up sushi and watch the notebook. She's bloated and feeling gross cause she's on her period. Just trying to be supportive.

Guy 1- Wow. Just wow.

oneginaman 

A oneginaman is a man whom has only been with one woman and worships her vagina because he cannot summon the energy to find another. He may also be seen as a type of AFC (Average Frustrated Chump). People like this will often remain in this state for a long time because of unconscious slavery. The solution? Go and fuck as many women as it takes for you to see this woman as what she really is. Just another fish in the sea.

Stop acting like a sissy you oneginaman.
