A「person begging」may still have some valor and pride remaining, but generally not much, although standing before the gate of a temple or shrine many hours on end every day, day in and day out, may be a valiant display,「person excruciating.」Nevertheless,「person standing beside a writhing beggar」cannot be praised as valiant.
Moreover, these elements may indicate two people, one standing beside another one prostrate and writhing on the ground. See 喫 describing a 'clenched jaw, mouth severing prick greatly.' Elements are「person begging for help」「person prostrated with bent twisted penis」「person and excruciating」immediately after being severely bitten by an angry bird chick while providing the art of fellatio services. Hence the VALOR and VALIANT behavior is not the male client, but instead the fellatrix service provider who finally displayed boldness and determination while facing great danger, being boldly courageous and brave enough to let everyone know she was FED UP WITH her life and living conditions, being willing to suffer the consequences and die, with「being fed up」here as in the English idiom, but in this case a geek literally biting off a chunk of meat and chewing, feeding as it were.
