Shouldn't we have a notes section telling us all about the idiomatic meanings of these slang phrases?
Yes I completely agree. Do we use this like I've got goose bumps or the hairs on my neck stand up, for example???
Maybe this only tells you that the elephant shivers
My guess is something like "Even something as large and seemingly-indomitable as an elephant can shiver". Just a guess :)
lập cập is the sound of teeth chattering. so "run lập cập" simply means to shiver, tremble, shake uncontrollably when cold or frightened.
The elephant is shivering should be accepted duolingo sucks
