'What's up' is not much used in the UK. 'How's it going' or 'How are you?' is more normal. If someone asks, 'What's up?' in the UK, it usually means: 'What is the problem?' For example, "What's up with you?" may be understood as quite an aggressive question meaning: "You seem to have a problem and that is annoying me."
あまりWhat's up はUKでは使われません。むしろHow's it going?やHow are you?が普通です。
もしイギリスでWhat's upと尋ねれば、「[何か問題でも](https://eikaiwa.dmm.com/uknow/questions/79856/)あるの？」というように解釈されるでしょう。
例えば、 "What's up with you?ときかれれば、"なんか問題でもあるの？そのせいでこっちは[気分悪い](https://eikaiwa.dmm.com/uknow/questions/51014/)んだけど？"というようなニュアンスに感じられます。
国や地域によって使う英語表現や捉え方が違います。
What's up?' usually means what's new or what's happening in your life.
Nothing much and same as usual are the simplest replies to the question.
You can, however, respond with a new event or experience.

Example
What's up?
Nothing much.
What's up?'とは通常what's new（何か変わったことは？）またはwhat's happening in your life（最近どう？）を意味します。
Nothing much（特に何もないよ）やsame as usual（いつも通りだよ）がこの質問へのもっともシンプルな受け答えです。
ですが、新しい出来事や体験について答えることもできます。

例
What's up?（最近どう？）
Nothing much.（別に）
"Nothing fresh on my end. "
You have nothing new to talk about.
" Same old same old"
Things are as they were when you last spoke to this person.
"Same as usual".
This means that nothing has changed.
This expression works best when someone is asking about what activities you are doing and you want them to know that you are doing what you normally do.
eg.
A: So ,what's up?
B:Same as usual I guess
A: I take it you're still at work at this time.
B: Yep
"Nothing fresh on my end. "
①「変わったことはないよ。」
新しい話題がないこと。
" Same old same old"
②「相変わらずだよ。」
最後に話したときから何も変わっていないこと。
"Same as usual".
③「いつも通りだよ。」
何も変わっていないことを意味する。
最近どんなことをしているか聞かれたときに答えるときの適切な表現。
例文：
A: So ,what's up?
B:Same as usual I guess
A: I take it you're still at work at this time.
B: Yep
A. 調子どう？
B. いつも通りかな。
A. 今職場でしょう？
B. そういうこと。
When you do not have much to say and someone asks "Whats up", you can reply by saying "Nothing much" This means that everything is okay but you don't really have anything to tell them.
You can also reply by saying "Same old" Which means that the same things have been happening such as going to work and going home and there is nothing new to tell them.
*Hey how are you doing?*
*Hey what's going down*
*Hey how you doing *
You can also say:
*How's it going?
*You okay?
*How have you been recently?
You can say whats up in English people will understand but it is more an American phrase :)
Hope this helps! ^ ^
*Hey how are you doing?*
*Hey what's going down*
*Hey how you doing *
以下のように言うこともできます。
*How's it going?
*You okay?
*How have you been recently?
whats upと英語で言うこともでき、理解してもらえますが、これはよりアメリカ的なフレーズです :)
お役に立てば幸いです! ^ ^
When he asked me what's up? I had to say not much...There's nothing going on right now!
The slang is "Wazzup?" "what's new ?" what's up? these are normally casual
conversation starters! However sometimes there really is "NOTHING to tell"
and so we might reply with "Not much!" Since in fact not much has happened!
スラングの"Wazzup?" "what's new ?" what's up? 「最近どう？」これらは、カジュアルな会話のはじめに使うフレーズです。しかし、本当に何も話題がないときは、"Not much!"「特になにも」と答えることができます。実際、何も起こってないですからね。
When someone asks what's up, they are asking what you are up to.
You can respond by saying that you are chilling, which means that you aren't doing much, you are relaxing.
You can use the last sentence when you are not up for chatting or when you don't have the time.
Chilling: hanging out, relaxing
"What's up Peter?"
"Hi, John. I am working on a school project so I am very busy, let me call you later once I am done."
"Chat later."
what's upとは、最近どうしていたかということです。特に何もせずにリラックスしていたよと答えることができます。また、話す時間がないときや、特に話すことがないときは最後の例を使うといいでしょう。
Chilling: リラックスすること
"What's up Peter?"
（最近どう、ピーター？）
"Hi, John. I am working on a school project so I am very busy, let me call you later once I am done."
（やぁジョン。学校のプロジェクトをしていて、とっても忙しいんだ。終わったら電話させて。）
"Chat later."
（あとで話そう。）
What's up の答えはいろいろな言い方ができます。
例えば、Nothing much と言うと「特に何も」のようなニュアンスになります。
Same as usual なら「いつも通りです」です。
例）
A: What's up?
B: Nothing much...
A: What's up?
B: Same as usual.
