From Proto-Finnic *kürpä (compare Estonian kürb, Ingrian kyrpä, Karelian kyrpä, Ludian kürb, Votic tšürpä (Pummala)). The word is first attested in the writings of Christfrid Ganander in 1786, with its first appearance in a dictionary dating back to 1848. The word is sometimes said to have originally referred to a lone, tall pine tree, or alternately a strong branch on a pine top, such as formed when the top was damaged but remained attached, and a side branch started growing upward at the spot. In light of the notes above, this appears to be an urban legend; it is more likely that the pine-related usage is a later development than the sexually related one.
