When someone says "bog off", what would it actually mean? Would that be an expression? Give me some examples, please!

What does that mean? What does "swing from the chandelier" stand for? OK. I already know what it literally means but seems like it's an expression also. Kind of a term in English. I just don't know.. Thanks

привет всем! всем привет! Я учусь на русский язык. И у меня есть общий вопрос. Что России люди думают о бразильских людей? Ну, я думаю, россияне симпатичный и забавный. Некоторые из них также имеют красивые глаза. Извините за мой бедный русский, кстати.

How long it takes me to learn a fluent English? Well, I'm studying English grammar and keep practicing the listening and speaking skills since very young, yet I can't consider myself good enough to express in English. People say I'm fine. However I don't feel that great.. it sucks :(

My lifetime in a box Everyone does what they are supposed to do, they never change their mind not even the most offish or understandable person on the planet. If they truly wanna do something, they will do it no matter what happens, people normally will do that till they just wipe out because that's a fact about human beings, so what do I mean by this? OK. I have been a wayward child in a while ago and this is why I am living in a box at the moment and that's quite true. I moved to here about 3 months ago and it's been annoying as hell because I have no peace, I have no entertainments, I don't have any friends either, and no one would come friendly to me, honestly.. I've been living a false life in here cause all the things I can see I can't actually touch. Kind of illusion and hologramatic systems around my body make my mind fly away from the current place to a better or worse, I don't know but once in awhile that's too good to get released of. Although I wanted to, by myself, come in to this huge white box, now it's been terrifying and never EVER thought it could be so exhausting and hallucinogenic, despite the good fake stuff I've tasted before I totally do regret. I want to bring my life back but I don't know how I just know I got an extensive story to share.
