Sticking my oar in, or catching and letting go of the crab
Last week some space was devoted to the crawling, scratching crab, so that perhaps enlarging on the topic “Crab in Idioms” may not be quite out of place. The plural in the previous sentence is an overstatement, for I have only one idiom in view. The rest is not worthy of mention: no certain meaning and no explanation. But my database is omnivorous and absorbs a lot of rubbish. Bibliographers cannot be choosers.
