Both Somila and Clare are correct. The term came from the American drug scene (and probably English, too) from the LSD crowd particularly. "What a trip!" usually meant a good drug experience, but could also mean it was a bad trip/experience - it really depends on context, or the expression and tone of the words. Unlike Mandarin (which I'm learning) English words can denote MANY different meanings depend on the accented syllable in the word, the tone of voice, or a facial expression. MUCH difference from Mandarin or Cantonese! I'm 65, so I lived through the 1960s and it's part of my vocabulary, but someone younger "not so much," which is another phrase meaning a younger person probably wouldn't use it.

I'm guessing that was an American, not British movie. I'm American and that's very common, but I can't imagine my English mates saying it that way. Good catch, Elena!

Perfectly acceptable in an email to a friend or in casual conversation. Not for university or college exams, unless the assignment is about using idioms/slang!

I'm currently improving my Spanish on Duolingo and italki. Useful, common conversational phrases are important to me. I'm not trying to be a translator or work for the United Nations. I want to be able to have an understandable conversation in Spanish. I'm also a flight attendant, so I like to get help with the announcements we commonly and regularly use onboard. You are Colombian? Don't tell anyone else on here (LOL!), but I think Colombians speak some of the most easily understood and beautiful Spanish!

Yes ... and no. The first one is more concise - clearer and shorter. And the second one is fine, but although I understand what you meant, a better and more correct way to write it would be: How are you going to do such a thing if you haven't had any experience with doing it before (or...in the past).

Sure, Arihant. I am American, so English is my first language. I live in the U.S. Eastern Time Zone.

Hello Aliona, I agree with Ami and Matthew. The phrase is much too informal for anything professional. Matthew's example (better option) is a very good one. But here is another thought I had - something that I personally watch because I am a professional writer. The phrase "and so on" or the abbreviation "etc" (et cetera - Latin for "an so on") is a bit of a cop out (being lazy, if you are not familiar with that term). It tells me that you might have just not cared enough to give me a full view! However, it can also mislead or misinform your reader. "My friends like volleyball, football, tennis, and so on," might make me think that the only sport your friends like are sports involving balls - in other words, they don't like skiing, archery, or surfing, which may or may not be true. Just another thought and probably much more than you wanted! Terry
