Define Hip To The Jive Meaning

"Does anything ever 'fall off ' the back of the truck? You know, 'Fall off'..."
"Yeah dude, I'm hip to the jive. And, yes, if the price is right."
(Jive: fall off truck = sell stolen merchandise from employer under the table for profit)

"Hey, on our way out we need to swing by Shorty's to pick up a couple of sticks. Are you listening?"
"Yes dear, I'm hip to your jive."
(Jive: sticks = joints)

I am reeeeeeal old and I still want you too think I am cool. So when I hear you using slang terms, that I have no idea whatsoever the meaning of, I will say, "I'm hip to the jive baby".

Hot Dawg, that dame you introduced me to sure is hip to the jive!
