What any Skater Dude creates when he rides his skateboard through a crowded city park inhabited by peoples' dogs. The dogs freak out and chase you down.
Man don't skate through that park at 6pm or you'll become dog porn
a porn dog is a man or woman that watches porn all of the time.
I came home the other night and my roommate Hershel was on the couch watching porn. Dude, that's all he does is watch porn. Hershel is such a porn dog.

FRIEND B (turning phone around): "no I was just using snapchat's new filter, see?"
