An event that is fired just before an Interest packet is actually send out (send is inevitable)
The reason for "before" even is that in certain cases (when it is possible to satisfy from the local cache), the send call will immediately return data, and if "after" even was used, this after would be called after all processing of incoming data, potentially producing unexpected results.
