means A person who plays the guitar, whether as a profession, hobby, or ongoing act of self-torture and optimism.

from Guitar traces back through French 'guitare' and Spanish 'guitarra' to Arabic 'qitara,' which itself descends from the ancient Greek 'kithara,' a stringed instrument plucked with a pick. The '-ist' suffix is the ordinary Greek-via-Latin agent ending slapped onto countless professions — so a guitarist is literally 'one who does the kithara-thing,' a lineage stretching from ancient lyre players to whoever is currently noodling through a drum solo at an open mic.
