The act of calling or texting someone while taking a dump.
Jake: "I should have listened to you about those burritos. It's like 'Alien' in my stomach. I bet you can smell it through the phone."

Nate: "Stop deuce dialing me. I don't want to picture you shitting. Ever."

Jake: "Stop answering my calls after we get Mexican food..."

Someone who talks on their cell phone while dropping a stink pickle in the can. This could be a male or female.

Talking on your cell, or texting whilst taking a dump. Then after finishing said dump, taking a picture of your poop with the cell and sending it to the friend you were texting/speaking to. Note: contrary to what many believe, deuce-dialing is not merely the act of talking/texting while pooping, but taking and sending a picture of the aftermath. No picture and you're merely having a conversation while you poop, not deuce-dialing.
You are talking to your friend while taking a dump. After the end of the conversation, you hang up, take a photo of the crap, and send it along to him/her. Congratulations, you're "deuce-dialing".
