Part of neurolinguistic programming is using phonological ambiguity.... in other words. When using pattern or in normal conversations these innocent words are perceived dirty by the mind, which can help get the conversation towards sex.
Some examples of these words are...
below = blow
new direction = nude erection
new day = nude eh?
two = too = to
wait = weight
but = butt
come = cum
More obvious examples are...
go inside... Like saying "I wanna go inside" (a building)
hard... "Yeah that might make it hard" (to do something)
wet... you get the idea
If anyone has any other examples share them with the rest of us.
