bare one's breast
- To make oneself vulnerable.
- […] he bared his breast to whizzing javelins, to hissing arrows, to any and every weapon that promised death and forgetfulness, and rest. (Mark Twain, The Innocents Aboard)
- I'm going to be angry with you. Pitch into old Frank Henchman--hit away, my young one.' And Frank put himself into an attitude as of one prepared to receive a pugilistic assault. He bared his breast, as it were, and showed his scars, and said, "Strike!"'(William Makepeace Thackeray, The Newcomes, Chapter 59)
