Nice but of Dutch etymology. An interesting tidbit is that they share there name with the French for dandelion (which English word come from another French term ‘dents de lion’ or lions teeth) which are called ‘pissenlit’ (also ‘piss in the bed’)

This is because the dandelion has a diuretic effect, it makes one urinate. For the woodlouse it’s different, they don’t make you piss the bed, but only make it smell like it. They secrete an ammonia like smell, which smells like piss.
