run aground
An expression from the Outer Banks of North Carolina, referring to one's being completely full or satiated after eating. It is a somewhat humurous reference to the large numbers of ships that run aground on the treacherous sand bars of the Outer Banks.
Example:
Bill pushed himself back from the table and said, "I can't eat another bite. I believe I've run aground."
