When you go to taco bell with your girlfriend and then you meet up with your friends and have a gang bang, however, if it's after you all pump cum into all her holes and she shits, it's a slippery toad
Oh man, we was doing my girlfriend last night and suddenly she did a slippery toad. My mom is gonna kill me if she finds out she shit in the carpet.
An idea that you have had, possibly of profound nature, that has been forgotten and is eternally irretrievable. Like a dead, ghostly, slippery toad that has slipped away from the recesses of your mind, never to be seen again. Hence, GHOST TOAD.
Renee Descartes: I think therefore I..... ah damn it! Not ANOTHER ghost toad!!!
