All thumbs has always meant clumsy, but it has new meaning in the age of hand-held smart phones. The term now relates to a poor
speller in text responses. Given the relative small size of keyboards, and the fact that people are texting only with thumbs, this can lead to many
typos. These typos are often compounded with
auto-correct, making them worse. 'All thumbs' seems to plague guys with large hands more than women.
