pispirispi
A pipe dream, a wild goose chase, or an imaginary problem that a person spends all their time obsessing over. The term comes from a story about a town fool who was always searching for something; when asked what it was, he called it a pispirispi but said he would only know what it looked like once he caught it.
When someone avoids their responsibilities by pretending to be busy with a secret matter only they understand, people say they are looking for pispirispis.
