Is there a word to describe the situation where you call someone and hang up so they call you back? The purpose of this is usually so that they get the calling charges.
I was thinking it's kind of like 'poking' or 'tagging' them? Like a 'poke/tag call'.
I voted on Tim Lewis' answer as it was the most interesting and it also suggested the answer which makes the most sense. Because we don't have a word for this in the English language, the word Ping can now be used as follows:
Ping (verb): the act of calling someone and then hanging up with the intent of having them call back.
Addendum: Based on this article Wayne Werner linked to in a below comment, the practice is known as beeping. This article lays out the reasons for beeping and the social protocol around it.
