a typo caused by typing too fast, when T9 uses a word spelled with the same keys but not the word you wanted, making your message rediculosly stupid.
Dana: hey call of later
Dana: sorry T9po call ME later
An error made in texting via t9 where a cell phone inaccurately predicts a word intended thus resulting in a different, often humorous sentence or phrase.
"Hey! I think my bombs are getting bigger!"
"Can you pick me up a candy car, please?"
("Bombs" and "car" are the t9pos)
