jokes in a tv-buy a vowel
million thanks to those who help ~~:)
[Chandler: you're my girlfriend, and that's what girlfriends should, should get.
Janice: Well, ①I gotta buy a vowel. Because, oh my God! Who, would've thought that someday, Chandler Bing would buy me a drawer.
Chandler: Well, not me. But that's what's happened, and, ah, and, and there's more. We should take a trip.
Janice: We should?
Chandler: Yep, we're a couple and that's what couples do. And, I wanna meet your parents. We should take a trip with your parents!
Janice: (laughs) I don't think we need to, because you're ②tripping me out right now! Are you okay?]

Q:1. Janice is surprised that her BF got her a present, and she’s about to say her catchphrase “OMG”, but why did she have to buy a vowel before saying that?
2. chandler said they should take a trip, so Janice said he’s tripping her out now, I kinda have a feeling that it’s a play on the word trip, but is “trip someone out” a real expression that we can use in daily English?

Answer

1.  There is a TV game show called "Wheel of Fortune,"  most Americans have watched it or are at least familiar with it.  In the game, contestants try to figure out words by guessing letters.  If they want to guess consonants, they just guess, but if they want to guess a vowel you have to "buy a vowel."  So there's a phrase from the show "I need to buy a vowel" or "I'd like to buy a vowel."
Janice is referring to that phrase.  Because to say "Oh, my God" she needs to say "Oh" which sounds like the letter "O" which is a vowel.  So she needs to "buy a vowel" in order to say her phrase.  ((It's her way of making OMG even bigger and louder than she usually makes it.))

2. "Tripping out" is a phrase that comes from the feeling that you get when you've taken an illegal drug.  If something (or someone) is tripping you out, they are making you feel confused and strange - like you're taking drugs.  Janice means that he's acting really weird and it's making her feel weird.
It is something you could hear commonly - but it's informal.  It's not something that you would ever say in a professional or formal context.

Hi Angela,

First, great job transcribing Friends. It is an excellent show for learning English .Here are the answers to your questions.

1) She said, "  I gotta buy a TOWEL" not vowel.  Chandler bought her a drawer( part of a dresser). It seems that she wants a towel to put in the drawer. If she has her own drawer and her own towel at his house, it is as if they live together. she feels like their relationship is getting serious.

2)"Tripping me out" is in fact a play on words. It is very INFORMAL and I would not recommend you to use it. 
Tripping me out is: To be confused, fascinated or stunned by something. it can carry either positive or negative connotations, but usually negative and that someone is making your feel strange.
3) He is tripping? Are you tripping?--- this means to be taking drugs and sometimes to be telling a lie. VERY INFORMAL.

I hope this helped you Angela. I would love to give you professional English classes. I have worked with Chinese English learners for 6 years now. Try a trial class!

Best Wishes,

Ms.Morgan
