Top definition
An idiom that means inexperienced or naive.

Its meaning comes from a baby that has just been born and is still wet "behind the ears" among other places.

This term might alternatively have originated on the farm, as it is said that after birth the last part of a foal or calf to dry is the area behind its ears.
"Those con artists thought they could make a quick buck out of me; they thought I was still wet behind the ears. But I showed them!"
