When something is so nice that it gives you the urge to cum on it with extreme vigor and force. These things can include but are not limited to wedding dresses, food, and white people.
You: "Dude that wedding dress is so cumtastical that I'm exploding in my pants just thinking about all the fabric I can ruin in one blow!"
Friend: "What in the actual fuck is wrong with you?"
