textonym

Two or more words that are spelled using the same series of keys in a text message.

"Me" and "of" are both entered using 6-3.

Also "good", "home", "gone", "hood", "hoof", and "goof" are textonyms.

My boyfriend was concerned when I texted him that I was nearly good. I explained that it was a textonym and I meant to say I was nearly home.
