for a person or animal to stick its penis into another person or animals vagina or asshole
he was so horny he had to hump something so he humped the nearest thing to him- his dog (who by the way is also a male). He grabbed the dog aggresively and tore down is pants and boxers at the same time, all the while pulling the dog closer and closer. Soon the positioned the dog over his erect penis and started humping. his penis went in and out, slowly at first then getting faster and faster, in out in out. the dog loved it and whined in pleasure. soon the dog wriggled out of his arms and the man smiled as the dog cirled behind him. He lay down on the couch and now it was the dog's turn. the dog lay on his back, pushing his penis into the man with pleasure and whining uncontrollably. When they were both done they lay happily together, side by side. "You truly are mans best friend" the guy said, smiling "and a heck of a good humper too." Then the dog and guy went at it in another round of humping.
bad, lame, boring
Damn that party was hump.
