as in what the fuck did you say?
This word was created in 1999 in a highschool AP Chemistry class. Due to the inability to talk in the small classroom, students typed conversations on their TI-83 calculators and passed them to other students.
Whajimoji was created when I was trying to type what, and someone kicked my arm and made me screw up.
It was humorous that whajimoji was created and is still used today...
