a rare phenomenon caused by the unrestricted spillage of guacamole dip. often caused by an exploding guacagrenade, the guacamole shower leaves everything in its path stained an avocado green, at least until the next rainstorm.
as lisa tried to pick up the serving bowl of guacamole dip, it slipped from her greasy hands and crashed to the table, strewing green stuff everywhere. "nice guacamole shower, lisa," tammi yelled, "i hope it rains soon, or at least before mom and dad get back from cancun."
