Sperm Whales are a bunch of whales that have sex in the ocean. When the whale gets horny it produces gallons of sperm that mixes with the ocean water.

Sperm Whales are the horniest whale species known to man.
Mom: Don't look honey.. those are two whales having sex

Why is the ocean water so salty?.. Probably because of them Sperm Whales

To get a head in a hot tub from a girl with a trachea and when you are cuming you jam your dick down her throat so that when she comes up from under water she blows your load out her trachea like a whales blowhole.
Curtis: Hey man, I made Tracy with the trachea do the "Sperm Whale"!

Nate: No way, "Sperm Whales" are the shit. Almost as good as a blumpkin.

2. A fat man who masturbates for a total of 24 hours in a fortnight (that may not seem like alot but remember that it's a TOTAL of 24hrs. Thats alot) and spews bucket loads of semen
Dave: "Woah! That guy is fat!!"
Bill: "Yeah, but his hands are covered in milk!"
Dave: "Umm... That's not milk, Bill. That's cum"
Bill: "What a Sperm Whale!"
Dave: "Bill, what's that mean, he's a Human!"
Bill: "Oh, it's a word that LemonyStuff invented."
Dave: "Woah, it all makes sense now!"
