I am of opinion, that a nip ith when you have a call of nature and would seek bushes or the backyard of your dwellings. You would pop when you pop! Like I when I milk a pigeon and I heard a pop sound. It wath someone who is trying to use a potato gun to make chips for hith fish and chips for supper and I would suggest him a nice Nerf gun for his wine and bread and my humble knife friend, Miss Augusta, would prepare the most refined gravy and brussel sprouts, for the most refined, intelligent man like I.
