cell phone punctuation 

The process or occurrence of non-verbally punctuating a conversation through use of a cell phone.

Cell phone punctuation can occur in many different ways. One example is when you want to get out of an awkward or undesirable conversation, you simply pull out your cell phone and start texting or doing any other miscellaneous thing. This gives the other party the clue that the conversation is over.
