YMF halloween candy?
Peanut butter cups
YMF childhood Thanksgiving?
Would’ve been 1975 or so. Lots of aunts, uncles and cousins with us that year - good company, even better food, a crackling fire and our old dog Pepper underfoot. Ah, memories…
YMF Thanksgiving food?
Stuffing with turkey gravy on top.
(Also, I distinctly remember Thanksgiving in 1975. My cousins’ grandmother (the mother of my uncle) said, “(Kenobi), please pass me a roll.” 10-year-old me pulled a roll out of the basket and tossed it to her. She did not catch it, but it broke up the table, and my cousins still talk about “that time you threw a roll at Grandma!”)
YMF astronaut or cosmonaut?
Sally Ride
YMF Communist or formerly Communist nation or republic (which includes “SSRs,” as in the Uzbek SSR, the Georgian SSR, the Estonian SSR, etc.)
I am very close to my aunt-by-marriage, and thus was close to her parents, so they were “Bobbe & Zayde” to me. My mother’s parents were “Grandma & Grandpa,” because my grandmother’s still-alive-when-I-was-born parents got the Slovak words. My father’s parents were “Saba & Safta,” the Hebrew words.
I love this! I was close to my uncle’s parents, too; though I didn’t have special names for them, except for Schatzie (German for “sweetheart”), which is what everyone called my uncle’s dad - to the point where the phone book in the small town in Wisconsin where he lived had an alternate listing for him in the white pages which simply read “Schatzie.” 
Bobbe & Zayde are the Yiddish words for grandma and grandpa, and it’s what my cousins called them.
Because the whole extended family lived in New York, and in a pretty small area, several “sides” interacted at the same holiday gatherings, and were even members of the same synagogue in some cases. There were lots of Passovers that would have my mother’s parents, and grandparents for as long as they were alive, my father’s parents, my aunt’s parents, my aunt’s sister’s widowed MIL, and her “unmarried” son, who finally came out to us, and brought his long-time boyfriend one year.

YMF Christmas ad that gets dragged out every year?
The Miller High Life “I’ll Be Home For Christmas” ad, which appears to date from 1981.
YMF Christmas ornament?
A tiny teddy bear that I put high up on the tree. Every year my cat jumps up and catches it, then carries it around the house like it’s her kitten. She doesn’t disturb the rest of the tree.
YMF holiday song?
Didn’t we just do this?
