means A ceremonial feast among Indigenous peoples of the Pacific Northwest Coast in which hosts display wealth and status by giving away or even destroying their possessions.

from From Chinook Jargon 'patshatl,' meaning 'giving' or 'a gift,' itself rooted in Nuu-chah-nulth and other Pacific Northwest Coast languages. The practice it names was central to the social and economic life of peoples like the Kwakwaka'wakw, Tlingit, and Haida — so threatening to colonial authorities' ideas of property that Canada banned it outright from 1885 to 1951. The word survived the ban and later widened in English to describe any lavish, status-driven giveaway.
