“PORNALITY” comes from PORN + BANALITY, a misheard or misunderstood (if clichéd) expression that takes on a more graphic or sexualized meaning:
Examples --
HARD-AND-
FAST solution becomes “HARDEN-FAST” SOLUTION;
NO-HOLDS-BARRED (
wrestling) becomes “NO HOLES BARRED” (stick it anywhere!);
NIP IT IN THE BUD becomes “NIP IT IN THE BUTT";
and, a pornality deliberately scripted for television:
CORNISH GAME HEN became "CORNISH GAY MEN" as mishead by Dick Solomon (John Lithgow) on NBC-TV'
s "Third Rock from the
Sun" (1996-2001).
