"good Luck With That"
This shows that courtesy is not dead. It's a very elegant urban code for, "I DONT CARE" but more accurately,"I REALLY DON'T GIVE A FLYING FUCK".
In some communities it means "YEAH, LIKE THAT'S GOING TO HAPPEN". So if something actually does happen you can never be called out and say it never happen.

Friend 2.You aren't logic minded enough to study computers,"good luck with that"!
