go-uppy thing = Escalator
Next?
I’ll go ahead and get these out of the way so that really creative types can get right into it.

I and up just swaping other words in and out all the time and leave the real one as an exercise for the listener. Sometimes by brain can’t keep up with my mouth 
The favorite of friends and family is we were going to go to the Cheesecake Factory, which, for some reason, I could not recall the name of. So instead I called it “The French Cake Palace”. SO now, that’s all any of us call it.
bubbly wine for champagne.
A friend of mine worked at the Airport. One day I inexplicably forgot that word, and asked him “Hey, how’s work at the … Airplane Factory?”. The weird thing is that he worked in a bank branch in the terminal, and did not repair planes or anything of the sort. Of course, now several of us refer to any airport that way.
You know those water worm things - the slippery toys that are water-filled plastic bags? My husband called it a machine once. It’s a lot of things but not a machine.
I once called the vacuum cleaner a lawnmower; my Darling Marcie seized on that and now, whenever I fumble for a word, she tells me the thing in question is a lawnmower.
Yer makin’ me giggle, that’s what I was going for… thanks! More! (French Cake Palace forever!)
Ha! I do refer to objects in that manner (“go-uppy thing” for “escalator” is very much like a description I would us, though I haven’t done that one yet) on purpose so that when I start to lose my mind, no one will notice.
For example, “climby thing” for rope, stairs or ladder.
Just… “THING”. And that goes for all parts of speech!
As in " I need to get a… thing" (pointing at longish hair).
Happens a lot with me.
Q
I sometimes refer to people whose name momentarily escapes me as "What’s-his-"prominent physical or psychological feature. I once had occasion to refer to an ex, for example, as what’s-his-neurosis.
Huh, I call all folks who’s names I’ve forgotten whats-his-butt or whats-her-butt, but matt has a much cooler version.
I frequently forget simple words like door. I’ll be talking and go “open that thing in the wall…you know, that hole in the wall where you walk…but not into the wall, into the hole in the wall, and it opens” and they look at me like I’ve got something worng with me.
I just usually describe what the thing does until I remember the actual word.
I was playing catchphrase with some friends. The word they had to guess was “bug collector.” What one friend guessed was “bugatorium”
Doomaflajee. (I think I spelled it properly…)
My usual method is to just go ‘uh, eh, er…’ while miming how you use the forgotten item.
I pray I never forget the word ‘dildo’…
Just today at work I referred to programmers as “non-artist people”. And yes, I am a programmer.
How often do you hear (I pray you don’t actually use yourself) thing as a verb? A guy I used to work with would always be thinging things, and just as often he would “take and thing” whatever it was.
Every once in a while I will almost say “take and do” or “up and do” when I will catch myself in time to avoid what I consider the ultimate faux pas.
When I was psych nursing one night I wrote in the report that “Patient A suffered a small contusion when he fell from his sub-upper-extremity-vertical-support apparatus.” Of course I was talking about crutches. It was not well received by the senior staff. Nor was my reference to an amputee being found “crawling on all three and a halfs” in the middle of the night.
