Definition
Catachrestical is the adjective form of catachresis, describing something characterized by the incorrect or strained use of words. Think of it as a word usage that's a bit 'off' but perhaps creatively so. It's not just a simple mistake, but a deliberate or forced application of a word. It often results from a lack of a more suitable term or a desire for stylistic effect. The effect can be humorous or confusing.
