The top definitions are wrong. Caked up either refers to:

1) Someone who has put too much makeup on their face, especially a concealer.
or
2) Being full from eating too much.

Has nothing to do with ass.
1) Amber went a little overboard with the makeup and her face was all caked up.
2) Timmy was all caked up after Thanksgiving dinner.
