Bongoist is formed from "bongo" (from the Spanish word "bongo", referring to a type of drum) and "-ist" (meaning a person who practices or is concerned with something). The word "bongoist" refers to a person who plays or is skilled in playing the bongo drums.
Think of someone who plays the 'bongo' drums — the '-ist' just means a person. A bongoist is someone who is skilled in playing the bongo.
