For folks that have been there, or nearby, it means you're pregnant. My ex was slightly pregnant (~10 months in. Yeah, I know) and sent me to the store for a specific ice cream flavor.
When I got there, that flavor wasn't available, so I got something similar.
When I got home, within minutes I fled back to the safety of the store, where I sought and found the manager of the Fred Meyer's, who upon hearing my sad and desperate tale gave me a tub of ice cream of my choice.
The pity in his eyes was palpable.
Edit: I think I survived with the free ice cream by adding a jug of dill pickles to the order.
Hahaha. Never have craved pickles. But, plums dried in salt. Mmmmmm.
