dolphin snack
When penetrating a female partner from behind and you go to sneak it into her ass and she tries to smack your cock away screaming "EEEE!" "EEEE!" "EEEE!" "EEEE!" In displeasure; sounding like a beached dolphin.
Damn dude, I tried to give your sister a dolphin snack last night and now my cocks bruised! Obviously she is not a fan of seafood.
