When someone uses the hands-free speaker-phone feature on their phone then holds it in their hand and up to their mouth like it was a piece of pizza they are about to take a bite of.
"Is that guy driving about to take a bite out of his phone?!?"
"Ha! No, he's probably just using his pizza phone."
"Wow. That's stupid."
