Men: What are you talking about when you talk about your "Junk"???

Ditto.
If it is “junk”, I got a knife - cut it off and throw it away, idiots.

Well, there is junk, and there is “junk”. One must be careful when considering when to “toss” one out with the garbage.

Like others here, I don’t refer to any body part as junk… but if I did it would refer to the complete set of male genitalia.
