What is pal around? How to use in English

The expression "pal around" has its roots in the mid-19th century, when "pal" was used as a slang term for a close friend or companion. The exact origin of "pal" is uncertain, but some theories suggest that it could have come from the phrase "fellow pal" (meaning a good fellow or a friend) or from the expression "palmer" (meaning a traveler who carried a pilgrim's staff). The verb "to around" also has a long history, dating back to Old English ("owerroundan," meaning to move about, surround, or enclose). The meaning of "to around" evolved over time to refer to moving aimlessly or idly, and eventually transformed into a slang term for hanging out or socializing in the late 19th century. The combination of "pal" and "around" to form "pal around" is believed to have emerged in the 1920s and 1930s, during the golden age of jazz and the rise of the urban vernacular. The expression has been commonly used throughout the 20th century and continues to be a part of modern slang today. So, in summary, "pal around" can be traced back to the mid-19th century, with "pal" originating from slang terms for friends and companions, and "around" being a phrase meaning to move aimlessly or hang out.
