1. The "Hanging Around" Theory:
This is the most common and likely origin. It's believed that "hang out" evolved from the phrase "hang around," which meant to "loiter" or "spend time idly." This usage dates back to the early 1900s, and the meaning shifted to "spend time socially" during the mid-20th century.
2. The "Hang Loose" Theory:
This theory links "hang out" to the surf culture phrase "hang loose," which emerged in the 1960s. "Hang loose" meant to be relaxed and carefree, which aligns with the social aspect of "hang out." However, the connection is not definitively proven.
3. The "Hang On" Theory:
This theory suggests that "hang out" originated from the phrase "hang on," meaning to "wait" or "stick around." It's argued that the meaning shifted to "stay and relax" over time. This theory lacks strong evidence, though.
4. The "Hang Up" Theory:
This theory is less common but proposes that "hang out" stemmed from the phrase "hang up," meaning to "end a phone call." It's believed that the phrase evolved to mean "spend time with someone" in contrast to ending a phone call. This theory is considered less likely.
In summary:
The most likely origin of "hang out" is from the phrase "hang around," with the meaning evolving from "loiter" to "spend time socially." While other theories exist, they lack strong evidence.
It's important to note that the exact origins of many slang phrases are difficult to pinpoint definitively, as they often emerge gradually and evolve through usage.
