Six-pack

Finn: Ahh, this is the life. Sun shining, birds singing—beautiful day here in the park, eh Feifei?
Feifei: Ah yes, fantastic. Just one thing, Finn. I'm a bit thirsty.
Finn: Yes I could do with a drink.
Feifei: An orange juice would be magnificent.
Finn: No, no, no. On a day like today the ideal thing would be ... an ice-cold beer, or maybe six ... 

(Looks in bag)
Finn: Ah—here we are. A six-pack! Look.
Feifei: Finn, I don't really want to see your six-pack.
Finn: What?
Feifei: Actually, you don't have a six-pack. You have a beer belly!
Finn: Oh, I get it! Very good, Feifei. In English the phrase six-pack originally refers to a way of selling cans of beer—buying six cans joined together with plastic holders.
Feifei: And now, as a slang expression, it can also describe the shape of stomach muscles ... on people who are very fit you can see six round muscles—which looks like a six pack of drink. Unfortunately, not on you Finn.
Finn: What are you saying?
Feifei: Anyone can see you don't have a six-pack. You have a one-pack—one huge beer belly!
Finn: Well, I think that phrase is easy enough to understand.
Feifei: Too many six-packs of beer, I'm afraid!
Examples
Feifei: So Finn, how about you leave that six-pack of beer and swap it for ... a healthy fruit smoothie!
Finn: Nice idea, and I can see a fruit smoothie seller over there! I'll go and buy two. See you in a bit.
