Heart Nut 

When the nut inside of your heart (it differs), explodes and creates a large ball of semen that spreads in your heart. It is done when someone says something caring/sweet enough for you to feel it in your heart. This also grants a personality change into a more caring person and super strength

Adam: “I really just wanna cuddle and kiss you under the stars.”
Jess: “Awwww baby. You just made my Heart Nut.”
