People respond to straight-shooter messages that don't rely on hollow lingual gew-gaws like "shining moment." Gew-gaws are a sure sign of someone who doesn't know his/her own message.
So for me, it doesn't matter who the phrase is pimping; I read "shining moment" and roll my eyes, thinking, "Who do you think you're kidding? Shining moment THIS!"
I see you like the working in darkness, no wonder Shining Moment irks you!
In my world Pimp was never a mainstream word, and it belong's to those who surely was NOT Improving The Shining moment more like tarnishing the moment!
BTW since you are from the other world "Improve The Shining Moment!" is from a Hymn!

On the contrary, if I were to start encouraging my clients to go for junk expressions like "Improve the Shining Moment," the result would be less business for them, less honesty for consumers who may need or want my clients' products, less work for me, and less prosperity for all.
A sanctimonious somebody lives in a nice cozy shell and thinks others who don't share it live in "darkness," but that somebody ain't me, I don't think!
