Mouth Saint Helens 

During oral sex, an ejaculation into a woman's mouth that's so powerful that it leaks out from the sides. Similar to Mount Saint Helens.

This chick was sucking me off last night, and I totally pulled a Mouth Saint Helens on her. I think some of it even came out her nose.

Mount Saint Helens 

When you shart and jizz at the same time.

Me and my GF just got back from Bernies Burritos and things got a little steamy in my car and in mid thrust I had a Mount Saint Helens. She then proceeded to lick my butthole.

Mount Saint Helens 

A sex act in which a male pours pop rocks into a female's anus, pours in some cola, and has anal sex with her without a condom.

I gave a girl a Mount Saint Helens last night. It was great until it erupted everywhere.

Mt. Saint Helens 

When one ejaculates in a woman's mouth (not necessarily named "Helen"), then the woman proceeds to do a headstand while holding said cum in her mouth, then she forces a sneeze causing an eruption out the nostrils.

My lady was on the rag so instead of sex she gave me a Mt. Saint Helens which erupted with glory.
