Resembling or having characteristics similar to a dartos or the dartos muscle.
From 'dartos' (Greek anatomical term) plus '-oid' (suffix meaning 'resembling or having the form of').
The '-oid' suffix is how scientists name things that almost match but aren't quite exact—like android (resembles human) or asteroid (resembles a star)!
