when a boy is bent over in your face...particually a girl and you shove a pencil or anything pointy up his butt when he least expects it and you say "corn dog!"
Greg is bent overin your face and you want him to move but he wont so you take your pen and poke him in the butt and say "corn dog!" He moves after that
The act of a man pulling his own flacid penis back between his own legs and shoving it up his own ass at which time he may try to make it erect nearly impossible or simply store it there for later.
when a male is giving a female anal and while his penis is all up in there she relieves her boules wrapping the males penis in feces thus making a corn dog
This is a very disturbing sexual act. A man eats a bunch of corn for dinner. Later that night he has hot steamy sex with a partner and takes a shit on her chest. The shit is full of corn and the male rubs his dick in it and then the female sucks him off. This is a corndog, my friend.
