Some friends cause hypertension, some cause inebriation and some, it is now confirmed, cause obesity. Or the opposite. The study concludes that skinny people, likewise, tend to make their friends skinny. In high school, you could have chosen a friend with a six-pack of abs. Instead, you chose a friend with a six-pack of Coors. And that, as Frost wrote, has made all the difference. (Time magazine)

What is actually meant by these two expressions?

a six-pack of abs=body building (üçgen vücut yapmak)
a six-pack of Coors= a kind of beverage like coca cola,pepsi (6'lı paket)

Aaaah! Of course!

Thanks, KemalKasap.

Never mind...

Precisely, "a six-pack of abs" is that sort of firm, tight stomach bodybuilders get ("abs" is short for "abdominal (i.e. belly) muscles"). As for "a six-pack of Coors", while it is a group of six cans or bottles packaged and bought together, it's not a beverage like Coca-Cola or Pepsi, it is a brand of beer ... and, as we all know, beer creates what is known as "a beer belly", so the writer is clearly contrasting a muscular stomach with a flabby one.

Never mind...

Just incidentally, "Never mind" is not really used as a reply to "Thanks". "No problem", "Don't mention it", or something along those lines is probably a bit better.
