Etymology
The word leacher comes from the verb leach, which originally meant 'to wash' or 'let water pass through' so liquid could carry things away. The -er part means 'one who', so a leacher is literally 'one who washes out' or extracts a substance by passing liquid through material, which explains the modern meaning.
