My problem with the phrase "My Precious Encounter" is that it seems to assume that the GM is framing situations in response to his/her own preferences, rather than those of the players.
"My Precious Encounter" refers to encounters which
(A) Are prepared before play which are so painstakingly balanced that they are inflexible in actual play: Their location can't be changed (because the monsters have tactics that sync with the location). Reinforcements can't be added (because the balance of the encounter would collapse; besides where would they come from? everybody else is tied up in their own precious encounters). (Taken to a sufficient extreme (as seen in some of WotC's products), the starting positions of PCs will even be forced in order to create the desired effect.)
(B) Encounters into which so much effort or emotional investment has been poured that they can't be be disrupted, changed, and/or avoided because they have become too precious to the GM.
So, in short, the phrase means absolutely nothing like what you claim it means. If you're flexibly framing, creating, and adapting encounters during play based on the choices of your players, what you're doing is pretty much exactly the opposite of encounters so precious to you that you refuse to change them.
