nuts

I'm a little stuck... Click here to teach me more about this clue!

But I can't explain it at all! Could you help me understand?

(Other definitions for nuts that I've seen before include "Crazy (from Brazil?)" , "Crackers - or what crackers are required for?" , "'Here we go gathering . . . . In May'" , "Slangily crazy like hard fruits" , "Fruit - bananas!" .)

I've seen this clue in The Hindu.
