This advice was offered by one gym rat warning another about spending too much time looking at the women in the gym. It’s a conflation of “keep your hands (or eyes) to yourself” and “keep your p**ker (d**k) in your pants”, both meaning to refrain from touching or gawking at another. This malaphor seems timely in light of the #metoo movement. Perhaps a new slogan? A big thanks to Verbatim for sharing this one.
