The act of flirting. While flirting, it is not uncommon for you to be uncommonly sweet, hence the term caking. Being abnormally sweet to someone you are "interested" in. Normally, said person, is of the opposite sex, but there are occasions when a girl might be caking to or with another girl, as a guy might cake to or with another guy.
1.)Hey, you'll have to do all that caking later, I'm ready to go!
2.)At the block party, Tony was seen caking with every available broad.
3.)How can I trust you, if you're gonna be caking with every chik on the block?
2. PDA (public display of affection)
3. Being whipped (You all up in your girl's face and she got you wide open)
4. When it looks like a guy traded in his playa card - he's acting a little too lovey.
For all of the above: usually denied by the person who was caking.
Guy 1: Look at him all pathetic! All cuddled up with Shaniqua. Yes dear, no dear, in her face... Guy you whipped.
Guy 2: What? Naw, Nigga you jealous!
Guy 3: Naw, dog, you girl got you open. That was some Betty Crocker Caking right there!
Man 2: Man dawg, do she really believe the b.s. you tell her?
Man 1: Naw...She know good and well that I only wanna smudge her.
