The massive food cravings experienced after a good smoosh (sex) session. Similar to the sensation one endures following a marijuana high, but without the drug-induced euphoria.
(Just finished having sex) "Ohh man...." "I've got the sexunchies." Or, when referring to someone familiar with the term, simply "Sexunchies."
