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.
She was no "butterfingers" now.
You have just permitted the cleverest rascal in the state to slip through your butterfingers.
Maybe you want something smaller, or with a rubberized backing to combat your butterfingers.
The plastic also a little slippery, so hopefully you don't have butterfingers, because that screen will shatter.
