the souvenir tail your ancestors had, now just a sit-down landmine.
means The coccyx is the small triangular bone at the very bottom of your spine — the vestigial tailbone — formed from several fused vertebrae.
from From Greek 'kokkyx,' meaning cuckoo. The ancient anatomist Galen looked at the little curved bone and decided it resembled a cuckoo's beak — so the cuckoo bird lent its name to the human tailbone, and the borrowing passed through Latin into anatomical English.
