The frothy fountain is when a guy goes for round two of sex after he has already came inside his girl with so much friction and air contact the cum from both people begins to foam in excess. When the right consistancy has been achieved, the guy is to thrust very hard creating a "fountain" effect. Splattering the cum where ever it may land. If he is lucky, double points if it lands on her face.
He received extra bragging points from his buddies when his "Frothy Fountian" creation splattered in his womans face.
The best friend of a mother who just had her baby. The baby calls the moms best friend "Auntie" even though there is no blood relation. You become a Fauntie.
I'd like to introduce you to my new son, he's 5 weeks old. And this here is my best friend in the world, met when we were 12, she's the baby's fauntie"
first you must understand what a donkey punch is. this would be like the next step. then you must get your date VERY drunk. while doing it from the back, in whatever hole you like, your date gets really sick because of the back-and-forth motion. continue to ride it like you stole it until she says shes gonna throw up. tell her to just do it. still continue to hit it until she vomits(hopefully repeatedly). while she vomits her abdomen will clamp down on your meat and two veg like a vice. viola...fountain of youth.

"i almost couldnt hold on for the full 8 seconds while i fountain of youthed with this chick last night."
