During the winter months, when you take a dump on a fat chick'
s stomach and try to burry your dick into her naval (
like a rabbit trying to burrow in a muddy hole). Your ejaculation simulates the melting of the snow, which allows the dirty rabbit (your shit covered cock) to then burrow in a dryer, more suitable burrow for the Spring (AKA the
girl's ear canal). During the Spring burrowing process, you are giving the
girl a dirty rabbit ear.
