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!"
I texted my friend to come over for a brunch but text went come over for a punch. After several back and forth texts to clarify I could see this was another textmess.
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.
