A dried up crusty penis. It would look like a wrinkely pruney finger after you were in the bathtub too long.
*Grandma was baking cookies one day when grandpa walked out of the bathroom stark naked. She exclaimed "By Golly! He has a Twat Dog!"
**After being in the hot tub for quite some time, Billy stepped out and was pantsed by a friend exposing his Twat Dog to everyone at the party.

a twat dog is when a male tries sticking his limp dick into a girls vagina, and it won't go in beacause it is limp like a hot dog, similar to whiskey dick.

When you put a cold, preferably frozen hot dog in a girls pussy when shes passed out, then it gets stuck in there. It WILL smell like shit in a few days without her realizing it.
