What is shouted at the moron driving a 4000 pound motor vehicle and attempting to talk or even text on their cell phone while in motion. These are usually people that cannot multi-task but are either too vain or ignorant to realize it. They are in need of support from the community to let them know what they are doing is going to get someone killed. This is done either with a middle finger, an angry look, a colorful suggestion in a loud voice or a bumper sticker telling them to "hang up and drive." Once being made aware, they should terminate their call immediately and put both hands back on the wheel and pay attention to traffic conditions.
"Hey, you just drifted into my lane because you are driving with your elbows while texting... HANG UP AND DRIVE!"
