Im calling it now: the line is said when Barry and someone else (my money is on Ralph) are looking for the Thinker's new secret base, they investigate someone house and all seems a miss until the other person goes "well, at least this house is bitching," then it's a closed up of Barry, the scene goes silent and he goes "Oh my days! This must be the place! Woah, thats a spicy meatball!"...

Yes, im also predicting he'll develop the catchphrase "thats a spicy meatball"
