A person who distrusts or lacks confidence in others; someone who is suspicious or skeptical.
From distrust (dis- 'not' + trust) plus -er agent suffix meaning 'one who does.' Formed in standard English word-building patterns.
A 'distruster' is someone chronically suspicious—and interestingly, if you've been burned before, becoming a distruster is actually a rational defense mechanism, even if it makes relationships harder to build.
