when someone is caught in the act of doing something wrong and all of a sudden don't remember seeing, hearing, or saying anything
When I came home and found the size 2 panties in my bed, he had the nerve to catch Helen Keller syndrome.

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.

It is when you are having sex with a girl missionary style and you punch her in the eyes, (so she can't see) smack her in the ears (so she can't hear), than karate chop her in the throat (so she can't talk)
The best thing happened last night.
What Happened?
I banged Jenna and gave her the Helen Keller Suprize! Then i broke up with her.
Damn talk about great breaking up sex.

grimace and steve playing pong in kristin's basement and the cups were set up all over the table randomly, as if Helen Keller set them up.

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.
