Indexting 

The typing of text (SMS) messages, esp. on a standard numerical keypad, using only the index finger of one hand. Is a relatively slow method for typing text messages and almost always requires that the cell phone be held in the opposite hand. Common among older cell phone users and possibly a cellular offshoot of the "Hunt-and-Peck" typing method.

Riding with my dad is scary enough, it's even worse when he starts indexting.
