Narrative:

While I was entering the area of branch county memorial airport (koeb) from the east; I was calling out my position on common traffic advisory frequency (CTAF); 122.70 mhz. I entered the traffic pattern with the standard 45 degree entry on downwind for runway 7. On the frequency; I heard other traffic calling out their positions for coldwater traffic and other airports. I paid no attention to that as this frequency serves many airports in the vicinity. As I approached the 45 and getting ready to turn left base; I saw a piper at my 8 o'clock (between me and the airport) making a left turn also toward branch county airport. I took evasive action and called out the traffic conflict. The pilot rudely informed me he was calling out his position for coldwater airport. On the ground; I called out on the CTAF that the AFD calls this airport branch county and not coldwater and there was a close call because they were using a non-standard name that only a local would know. I was told on the air that it is called both and they continued using the non-standard name.

Original NASA ASRS Text

Title: A multi-engine pilot reported an NMAC occurred in the vicinity of OEB airport; in part because local practice in airport terminology (locals call the airport 'Coldwater') differs from the AFD name (Branch County).
