When you and a girl drunk as hell in the bathtub or jacuzzi with a chick that you know doesn't like anal and try to have anal sex with her. She shakes her head and makes sounds like a dolphin would as you try to stick it in her ass. "Ahhkaa Ahhkaa Ahhka" like a dolphin, hence the slippery dolphin!
"I tried the slippery dolphin with that drunk hoe last night but she wouldn't let me!"

When a guy is fucking his girl from behind and his dick slips out and accidentally penetrates her anus causing her to arch her back and scream "eeeeet, eeeet, eeeet!"
