After making love, a man ejaculates on his partner's anus. After ejaculation is complete, the partner expels gas through their semen covered anus. This causes a "spouting" phenomena similar to that of a whale during its normal course of breathing through its blow hole.
Man: I just blew my load on your ass. Get ready to fart!
Partner: Get the camera ready. Here it comes!
Man: I can't wait to post these pics. What a perfect Baby Beluga!

Get the Dying Beluga mug.
Blue balls that have swelled up to the size of a whale, especially a beluga whale. A single cumshot from a penis attached to a set of Beluga Balls can cause a person to contract Moby Dick.
The next time I nut with these Beluga Balls, I'll be known as a sperm whale.
