when on a beach (preferred, but may also partake away from the beach)when a woman is on her knees and forearms and her hands are in the praying position, and the guy kneels behind and proceeds to stick his wang into her anal orphace until he gets sand (or excrement)on his member, therefore being (beached)

A beached whale is a piece of poop so large that it leaves the water of the toilet. This usually leaves a mark as well because the poop touches directly onto the dry part of the toilet. It can often be bragged about between guys. However, girls will not be impressed by the feat of a beached whale and will most likely result in her not wanting to have sex with you.
Guy 1: Dude, I left I huge beached whale in the toilet yesterday. It was like the third one of my whole life.
Guy 2: Awesome, you should have taken a picture.
Guy: Hey, I have a picture of the beached whale I left in the toilet yesterday. Do you want to see it?
Girl: Ew, you're disgusting. I will never have sex with you.
Guy 2: Awesome, you should have taken a picture.
Guy: Hey, I have a picture of the beached whale I left in the toilet yesterday. Do you want to see it?

The act of lying sprawled-out and helplessly on one's back after ingesting so much food, the fullness is almost unbearable.
After spending two hours at the local all-you-can-eat buffet, Billy says to Bobby,
"I don't think I can walk out of this place; I'm going to have to beach whale it here for a while."
