Ok, time for the promised interpretation of Newfie talk.
How's ya gettin on me ol' cock? What's ya going at? Down on Garge gettin on 'er tonight or wha? Ya knows b'y!"
How's ya gettin on, me ol' cock? = How are you doing, my friend?
What's ya going at? = What are you planning to do tonight?
Down on *Garge gettin on 'er tonight or wha? = Going to George Street to get ridiculously drunk?
Ya knows, **b'y! = Of course you are!
* "Garge" is what the infamous George Street is often referred to. Many Newfoundlanders drag their O sounds out like A sounds, making George sound more like Garge. "Garge" is a world-famous street here in St. John's that consists of nothing but bars. It's just 2 blocks long, with 22 bars. It's holds the record for having the most bars per square foot in North America, or something like that.
** B'y is a
very common Newfie slang. It's literally "boy", but pronounced "b'y". We use it like most people would use "man". Like, "How's it going b'y?"
