A chick gives two blow-jobs at the same time, resembling walrus tusks. (This works better with a larger girl, thus the walrus, but does also work with any size.)
This is a sexuall act in which an obese man lays on top of a woman without holding himself up allowing all of his body weight to smother her, he then proceeds to fuck her while she fights for air. To complete the walrus you must make the necessary grunting noises similar to a walrus. Please note when finished you should check for signs of life.
Optional: This can also be done during anal, known as the reverse walrus, clapping like a walrus is also acceptable
