Thingie, thingiebobber, that thing right there…
Also, “this guy.” “See, this guy goes into this guy and then you bolt it down using this guy over here.”
woss’name
Fucker-thing. Or if it’s vitally important and urgent that you describe the right object and still can’t think what it’s called: fuckin’ fuck thing.
I was innoculated with this one by my platoon sgt in 1994. I haven’t been able to lose it.
Whoziwhatsit.
“Hoo - zee - wot - sit.”
Whatjadoodle
Or thingy.
“WHA-cha-doo-dle,” BTW.
Surely my family isn’t the only one that says “Whatjadoodle” (???)
Oh yes, we do :). And sometimes, we even call them “gogosses” or even “bébelles” :eek:
I say “thinger” as well when I can’t place a name to something.
When I hear or see something puzzling, I say “urbur” (rhymes with berber). It has to be spoken with a slight Tim the Toolman Taylor voice.
Flinky-doodley.
Thingy.
Whatsis. (Person: Whosis.)
You-know-what.
Gootchkie.
Hibby jibby. Or jibbies if there’s more than one.
Chingas…or Gizmachie.
Thingie. Thingamajob/Thingamajobber. Thingamabob/Thingamabobber. Doohickey. Dealie. Dealie-whatsit. Hoosie-whatsit. Dealiebob.
Dealiebopper or fuckin` thing, depending on present company.
For items I can’t remember the name for, I call them thingamajiggers.
For people…
What’s her/his bucket.
That usually gets an odd look out of people. Never heard anyone else say that and I’m beginning to wonder if I’m crazy.
:eek: What a strange word. Apparently common, since Faruiza mentions it later.
Doohickies…whatsherface… <point>
In polite company, I say “what’s his (or her) nose.”
Among good friends, I sometimes say, “what’s his dick” or “what’s her tits.”
Usually good for a brief and perplexed pause in the conversation. 
Heh! It is sort of common, at least around here. I’m not sure of the spelling of the long version of that word, but it has always sounded like “chinga-dera” to me. That and the shortened version, “chingas” are both spanglish slang.
Hoe-heet-ut.
Dingetje/ding/dinges.
For people: female: Dingetje, male: Dinges.
Funny thing is, people will understand what you’re talking about when you ask: "Where’s that dingetje I left on the cupboard?’’
