bonkers
Off one's rocker
Bonkers means crazy or mad, used informally and usually without serious clinical implications: The whole plan sounds bonkers, She went bonkers when she found out.
British in origin but widely used.
The tone is typically playful rather than harsh—you might call a friend's idea bonkers without real insult.
