I looked it up and there's no special meaning to his name that makes sense, Keith means wood, and mojito either originates from 'mojo', a cuban seasoning made from lime, or it could be a derivative of the spanish word 'mojadito' (lightly wet) which is a derivative of 'mojado' (wet). If we're really stretching it then maybe his name could be Naptha (meaning wood alcohol), but I wouldn't bet on it
