0 a person who drops things they are carrying or trying to catch:
[ as form of address ] "Butterfingers!" she called as I dropped the hot plates.
The plastic also a little slippery, so hopefully you don't have butterfingers, because that screen will shatter.
Maybe you want something smaller, or with a rubberized backing to combat your butterfingers.
You have just permitted the cleverest rascal in the state to slip through your butterfingers.
She was no "butterfingers" now.
