Where does sicko come from?


Sicko is based on sick, which has described someone as “perverted” or “repugnant” since Old English. It features the suffix -o, used in other such insulting slang terms for people as weirdo, wino, and pinkoThe term was recorded in 1977, preceded by sickie and sicknik. (We wish sicknik has stuck around.)

In 2007, Michael Moore released his documentary, Sicko, about problems with the US healthcare system. Elsewhere in politics, sicko has also become a popular way for some armchair critics to characterize Donald Trump since his election in 2016, although Trump himself notably called the February 2018 Parkland, Florida school shooter a sicko.

In 2018, rapper Travis Scott gave sicko a massive signal boost with his Billboard #1 single “Sicko Mode,” where featured rapper Drake says Scott is in “sicko mode,” a slang way of saying he’s at the top of his game. Sicko, here, seems to be behaving as the slang-inverted sick for “extremely good.”
