Caking is when a guy is dealing with a whore, slut, or anyone he simply wants to fuck and instead of taking the 'hard no' (rejection) or fucking her and leaving, he instead sticks around and takes care of the financial responsibilities, plays 'daddy' to her kids, and/or pretends he's smitten with her.

He's even BAKING CAKES with this woman (hint: that's why we REALLY call it 'caking').

Essentially, it's a man placing himself in the most servile position by going far and beyond what's needed just to get some ass; he's attempting to 'buy the cow' with deeds and gestures WHEN THE ENTIRE NEIGHBORHOOD'S getting free milk, cheeseburgers, and leather jackets.

To have a very big butt that makes your body looks nice, but not fat.

To dry hump.

Only extremely attractive people may call it 'caking' though.

When a guys is all up a girls ass, wasting his time, money, and efforts on a girl that is not really into him but only into what he has to offer to her.

The late night desire to purchase random combinations of food such as cheese and cake. This my be confused with the munchies but it applies specifically to a combination of foods that include cake. People with this affliction gather in small groups to purchase said items. One HAS to be gay.

Using only dry toilet paper, not finishing the job with a moist flushable wipe after pooping resulting in microbes of shit being unknowingly left caked around one's asshole.

goofing off, being silly, klutzy, messing up. Stems from common stereotype in pop culture of people failing at baking cakes, falling into them and destroying them, and/or cake ending up in the wrong person's face in silly food fights.
