"G'luck to ya" sounds like there's a Glock aimed at your head but I swear
that's just the sarcasm talking.
"G'luck to ya" is an abbreviation of "good luck to you" which is sometimes used ironically to mean "that's unlikely" or "I'm not with you". When used sarcastically it expresses doubt, disapproval or lack of confidence.
Rolling down the street, like a die on the table, what you roll, is what you get, the number shows, unbeknownst, surprise arrives, a hint of beauty cross you, you can't believe your luck.
