Are You "Hot on the Sauce"?

SCENE: Ransom (7), Ruth Love (6), Camellia (4) and I drinking hot chocolate and coffee at Java Burrito this morning.

Camellia (@Java Burrito 2.5.15)

RUTH LOVE: Mom, I've got a new expression. It's "hot on the sauce."

ME: How would you use it in a sentence.

RL: Your new hair do is "hot on the sauce."

CAMELLIA: Or, Java Burrito is "hot on the sauce." This hot cocoa is awwwwwesome!

RANSOM: Or, I feelin' "hot on the sauce." Today's gonna rock.
