“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).
.
"Man, you got a buttload of mail."
"
Don't you
mean 'boatload'? "Buttload" is a pornality."
"I was gonna say 'shitload'."
"
Point well taken."
