Paul:'Hey Jenny, why is your face all red and smells like tuna?' Jenny:'Vera and I both have unusually large labia, thus, she salmon slapped me this morning with them'
The act of slapping someone on the forehead with the bottom side of the head of your penis after facial ejaculation. The bottom side of your penis looks like the neck of a salmon, hence the term "salmon stamping".
Salmon surfing is when you jump as high as you can with arms down at your sides in front of family and/or friends. And then launch yourself onto a crowd of humans.
When a person with an uncircumcised penis sticks the head of it to the receivers skin, then slides the foreskin over the head and holds it to the skin. While holding the foreskin in place, they pull the penis back away from the receiver, causing a suction cup with the foreskin. When it is released, it makes a "pop" sound.
