The De-Big-U-Later was an invention in the world Lisa created as a result of zapping a baby tooth in a dish of coke with static electricity. They used it to shrink her to their size. Although this machine made her shrink, the idea of a Re-Big-U-Later was considered crazy.

It later appeared in the episode The Blue and the Gray where Marge used it to shrink her hair.
