So what exactly is Creddie? Creddie is the romantic pairing between Carly Shay and Freddie Benson.
Key word: PAIRING.
Creddie is when Carly and Freddie show romantic feelings towards each other, making the Creddie PAIR. When Freddie is flirting with Carly, it is not a Creddie moment unless Carly RETURNS the romantic feelings towards Freddie.
