meatball pocket

a meatball pocket is when you are doing a girl in the ass and then you jam you nuts into her butthole

At the point of male/female relations, the male subject is unable to perform due to heavy drug and/or alcohol intake. At that point the male subject proceeds to throw his flaccid penis and genitals into said womans privates. Thus creating a flabby mold closely resembling a meatball. More times than not this technique does not work and leaves said woman extremely unsatisfied and unamused.
