What is "serbomans"

Serbomans (singular Serboman) was a Bulgarian pejorative term used by Bulgarian nationalists for inhabitants in the region of Macedonia that claimed Serbian ethnicity (declared as Serbs) and supported Serbian national ideals at the beginning of the 20th century. It was also used pejoratively by Bulgarians to refer to Macedonians who refused the Bulgarian national idea. The origin of the term is unclear. It first appeared during the time of the Serbian-Bulgarian rivalry for present-day Macedonia. Serbian nationalists used the term Bugaraši for Macedonian Bulgarians, supporters of the Bulgarian Exarchate.
