Define Golden Opportunity Meaning

This is my golden opportunity to redeem myself.

"Dude, did you bang that chick last night?"
"Yeah bro, but I was so wasted I pissed the bed"
"Did you blame it on her in the morning?"
"No, why?"
"Then you, my friend, missed a GOLDEN OPPORTUNITY"

I blew a golden opportunity when I left my homework pass at home after deciding not to do my homework.

Friend - you gonna Golden opportunity in Buffalo tonight?
