Drunk Dialing

Drunk dialing is a pop-culture term denoting an instance in which an intoxicated individual places phone calls that he or she would not likely place if sober. The term often refers to a lonely individual calling former or current love interests.

I have this disease late at night sometimes, involving alcohol and the telephone. I get drunk, and I drive my wife away with breath like mustard gas and roses. And then, speaking gravely and elegantly into the telephone, I ask the telephone operators to connect me with this friend or that one, from whom I have not heard in years. —Kurt Vonnegut

"Drunk texting" is a related phenomenon, and potentially yet more embarrassing for the sender as, once the message is sent, it cannot be retrieved; the message will most likely be misspelled (due to being drunk), and it might be reviewed and shared among many.
