Pat Cuff
A "Pat Cuff" refers, generally, to a quick or cursory search or examination of someone, typically for weapons or contraband. It is often, though not exclusively, associated with law enforcement or security personnel. The term implies a less thorough search than a full body search, focusing primarily on the exterior of clothing.
The "pat" refers to the act of patting down the individual, and the "cuff" is a possible abbreviation of "cuffing" or handcuffing, suggesting a potential outcome if something illegal is discovered during the pat-down.
The legality and justification for performing a pat cuff are subject to laws and regulations which vary by jurisdiction. Generally, a "pat cuff" requires reasonable suspicion that the individual is armed and dangerous.
