'Acerbic' is a strange word, fully accepting and embracing of how intensely mongrel-ish it is. That mudblooded lovechild of 'assorted', 'acidic', 'asserted', and 'sherbet'. But the meaning of the word, a·cer·bic /əˈsərbik/ (Adjective):  (esp. of a comment or style of speaking) Sharp and forthright, fits snugly into the smell and shape of the word itself.
Like a recently thawed Scandanavian with a small wooden hammer and a large grudge, who asks you to introduce him to a lovely canoe so that he can reclaim the word 'kiosk' from those fat fingered bastards robustly proportioned persons of diverse and mysterious heritage.
