A poem is a piece of semiotic sport, in which the signifier has been momentarily released from its grim communicative labours and can disport itself disgracefully. Freed from a loveless marriage to a single meaning, it can play the field, wax promiscous, gambol outrageously with similar unattached signifiers. If the guardians of conventional morality knew what scandalous stuff they were inscribing on their tombstones, they would cease to do so immediately.
