Where does hard-on come from?

To be hard (on someone), or “to be tough on or critical of,” has also been around since at least the 1860s. Hard, here, implies unfeeling treatment. In the 1950s, hard-on was slang for “tough” or “aggressive” behavior.

Hard on for “sexually aroused” is evidenced in 1893, as in He was hard on for her. By 1922, the word had become a noun for “erection” (e.g., He had a hard-on). Erect penises are characterized—if you need us to spell it out—as hard.

By the 1990s–2000s, hard-on had extended (no pun intended) to intense excitement in nonsexual contexts (e.g., You have a hard-on for McRib sandwiches).
