Having your sexual overtures preemptively deterred by your partner wearing a pair of ratty old (usually flannel) pajama bottoms to bed. Not to be confused with getting pantsed, it is the opposite of peacocking. Whereas peacocking is defined as dressing for attention, just as peacocks use their feathers to attract a mate, PJ pantsing is a conscious effort to dress down, thereby sending a clear signal to your prospective mate that there will be no nookie tonight.
I thought she was in the mood after a couple glasses of wine, but when we got to the bedroom she PJ pantsed me, rendering me flacid in no time.
