What Does JUNK Mean?

Male Genitalia

Especially in the US, the word junk is used as slang for the male genitalia.

The origins of the term are uncertain, but it sprang to public attention in 2010, when John Tyner, an American computer programmer, refused to enter a body scanner at San Diego International Airport (SAN) and was obliged to submit to a body search. Tyner agreed to the pat-down, but said "If you touch my junk, I'm gonna have you arrested."

The encounter with the guard was recorded by Tyner on his cell phone and posted online. The video went viral and was used by conservative politicians and media outlets to attack the security policies of the Obama administration.
