Immortalized by an Eddie Murphy bit, "Have a Coke and a Smile" was a Coca-Cola ad campaign in the early '80s.

In Eddie's bit, Richard Pryor tells Bill Cosby (who did Coke ads) to "Have a Coke and a smile and shut the fuck up).
Richard: Do the people laugh when you say what you say?
Eddie: Yes.
Richard: Do you get paid?
Eddie: Yes.
Richard. Then tell Bill I said have a Coke and a smile and shit the fuck up, the jello-pudding-eating motherfucker.

The late afro-american comedian Richard Prior coined the phrase a long time ago. The phrase is "Have a Coke and a smile and shut the F__K up!"
"Are you talking to me? Why don't have a Coke and a smile and shut the F__K up!"

Whack slang coined by Bizzle (of LG) purportedly describing his 'game' whilst out clubbing. Now peep this, Bizzle doesn't drink, so his 'game' is to hold a glass of coke, and with a cheesy grin (and gift of the gab) attempts to coax the ladies. Yes, ladies and gentlemen, it's A-B-C slang of the finest order, which has hopefully been put to bed (R.I.P), because it sux!!!

Caveat: Bizzle does actually have 'game', it's the slang that's weak!!!
Freezee: What's the deal for tonight?

Bizzle: Nothin', mayne, hit the club - usual antics.

Freezee: Are you shacking (drinking)?

Bizzle: At'all (No), I'll be there with a coke and a smile.

Freezee: Bloody 'ell!

Your favourite mixed drink with coca cola, often camouflaged by being drunk from the original coke bottle.
At a break in the epic motorcycle journey, Ripper produces 2 plastic bottles of coke from his luggage & offers one to the exhausted Zero.

Zero: "jeez mate, that's strong, what did you hide in there?"
Ripper: "yours is Captain's Spicey & mine is Jack - just coke and a smile"
