The act of inserting an egg into someones rectum as they are sleeping, or passed out. Upon reawakening they automatically clench their buttox in surprise of the foreign object causing it to break, therefore releasing large amounts of gooey brown and yellow "egg salad".
While John slept Timothy, and Anthony gave him a rearend full of egg salad.
Heavy salad is the saying of when one is feeling down with life. When one is down, just curse, instead of abuse about somebody that you hate, just mention heavy salad.
