Well, I think the simplest answer to your quandary ref. not wishing to utter a line from an advertising slogan is not to use it in the first place, as it's also a bit of a cliche even in its original version.
I am merely a sprightly 60, so clearly not one of your generation, as I had long straggly hair, loon pants, kaftan & a beard when a youth, rather than a greasy quiff, bootlace tie & drainpipe trousers favoured by those 10 years older than myself wnen I was 18 (& that was only the girls, as I remember, but then, my memory's not what it was).
HOWEVER. It is possible to use unconsciously a word or phrase from an advertising slogan which has been adapted & adopted, in every day conversation.
I cite the fact that I sometimes use the word "Simples" instead of 'THERE!' or 'QED', to mean "It's obvious, & my train of thought is thus demonstrated".
This comes from the end word from a series of current (last 4 or 5 years) UK TV adverts for an internet insurance price comparison site featuring meerkats.
Dunno if you get it down under, but hope you don't.
Some genius marketing bod noticed that his client,
http://www.comparethemarket.comcould, if spoken by an Australian or New Zealander, sound like
http://www.comparethemeerkat.comSo a whole raft of adverts were & are run featuring a meerkat with a Russian accent patiently explaining that if you wish to compare meerkats, go to the latter site, but if you want to compare car insurance prices, go to the former.
Why a meerkat should have a Russian accent when speaking English or why one would want to compare meerkats is beyond me, & natch, the insurance website created the comparethemeerkat site after its own, but it's final word, 'Simples' spoken like "
SiyImplz" by the meerkat, has now become market (or
meerkat) leader here.
Pure genius. & the idiom has now been adopted here & everyone understands what you are referring to.

I may be bonkers but at least I'm British.
