to go out in public without any boxers/briefs underneath your clothes so your junk is bouncing around for all to see

I saw Arnold Schwarzenegger walk the dinosaur on TMZ.

What fail trolls on 4chan use to end stories that sound interesting to entice readers.

I met someone in the night who had a unique character and personality. She hinted that she wanted a night with me, so we went to her apartment. There was a little light next to the door, I turned it on. She then unlocked the door using her keycard. I chose to open the door, get on the floor, everybody walk the dinosaur.
