盛り上がる can mean many things from "to excite" to "pile up" depending on the context. The 「っちゃお(う)」ending usually means "Why not..." or "Let's go for it." So if you put that together you get something like, "why not go ahead and live it up with your friends" or something like that. It's really hard to tell without more context.

So, from there, you need something to learn. I would recommend using a comprehensive system (like a beginner textbook with CDs or an online lesson program). That will take you through beginner grammar and vocabulary in an ordered manner. It is hard to just study random information. Better to have a syllabus or plan to follow. Then, once you have studied a little bit, you will have something to talk about with your teacher or language partner. I like the japanesepod101 site a lot because it breaks everything down into easy 15 minute lessons. If you are more in the mood for a textbook, "Genki" or "Minna no Nihongo" might be good. Either one should be available from Amazon. Good luck!

In addition to what hana-san said, "うちえ" is actually a mistake. It should be written "うちへ". The pronunciation is the same but you write it differently when it is the particle "e" (to, at, etc).

Hana is right. Many Japanese company titles don't have direct translations in English. In my company, we have a "President" and we call him 「社長」in Japanese. But we are a subsidiary, and our parent company's president is also called 「社長」in Japanese. I usually call our parent company's president "CEO" in English and the subsidiary company president, "president". For the higher up positions, I usually reference this site. http://www.studio-cube.com/bizinfo/title.html

This doesn't really make sense in English. Do you mean 1) "I hate how most people leave when I am talking" or 2) "Most of the people I hate leave (the room) when I am talking" or 3) "I hate people who leave the room when I am talking"? -- In 1), most of the people in the room leave when you talk. In 2) the people who you already hate leave the room when you talk. In 3), you start to hate people when they leave the room when you talk.

I thought it might be Jisho's fault ;) I love the site, but only when going from Japanese to English. When you are trying to find a Japanese equivalent for an English word, it is about the worst thing you can use. It has all these extremely rare and uncommon words and it does not distinguish them from common ones. Can I recommend http://www.alc.co.jp/ and http://tangorin.com/ ? The first is great for looking up phrases, slang terms, and idioms. It is actually not a dictionary, but a compilation of translations that you can search. The second is actually a good dictionary with lots of example sentences. Remember, whenever you are trying to look up an English word in Japanese, always double check Japanese to English to make sure the definitions match.
