The ability to nimbly use the keys for texting; phone prowess for the digital age.
After fumbling with the cell phone for several minutes, my daughter took it away from me, quickly sent the message and told me, "Dad, you have no texterity!"
Someone who can't keep a conversation going through text messaging. Texts boring things and phrases such as "K", "Cool", "What's Up", "Nothing Much", and "Hbu". Is awkward, even through the phone.
He was such a drytexter on instagram direct message last night.
