The totally over the top and crazy reaction normally calm children have when they can't fit the Lego together perfectly, or if someone touches their Lego.

Handle Lego-rage with care for any attempt to calm the child in question will result in you being the target of the rage, no longer the Lego itself.
Bob was playing so nicely at playschool then the Lego-rage hit and chaos followed. So embarrassing as headless Lego men were thrown at the staff.
