"Don't touch my junk" is a phrase that became popular in the United States in 2010 as a criticism of Transportation Security Administration (TSA) patdowns. The word "junk" is American English slang for a man's genitals. The phrase refers to the offense many people took to the November 2010 decision by TSA to begin full body patdowns of airline passengers in the U.S. who refused to go through a full body scanner.

The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within, and connecting to, the United States. It was created as a response to the September 11 attacks to improve airport security procedures and consolidate air travel security under a combined federal law enforcement and regulatory agency.
