Papi or Papito.
My sister and I used “Dad”, but Mom and her siblings used “Pap” or “Pappy”, and Dad himself used “Pop” for his father.
Called him “Daddy” until I got to about college age and started calling him Dad.
White southern girl, mid 30s. So it comes out more like “deddy” or “daeeee-di”
I find the lack of “Pop” odd, since it’s used fairly often in fiction.
I’m polling, actually, because I’m writing a first person narrative and I’m trying to decide how the character refers to his father. I had considered “Pop,” but I wondered if its use in New England in the 1960s would be unlikely.
Seems its use anywhere is unlikely.
I called him “Mark” (his name) once.
Once. :eek:
I don’t know anyone who called his father “Pop”, “Pa”, or “Papa”. I never would have considered it – it seems weird.
Besides “Pop” was reserved for my grandfather.
95% of the time it was “Dad.” The other times, if I knew what was good for me, it was “Sir.”
Southern WASP.
Dad, 1960s, WSAP, Southern Ontario, Canada.
Other: “Sir” I’m an Army brat.
Same here, except I’m a WASP (White Anglo-Saxon Pagan) 
“Pop” always sounded terribly old-fashioned to me.
Edit: my mother’s father was “Grampa” and my father’s father was “Granddad” (except he passed on before I was born, so I never spoke to him, just about him).
Dad, late 40s, midwest.
Mom was usually Mom, but I would at times call her Ma because it got her goat
You did not.
“Appa” (/əpə/, homophonous to “up a”). Tamilian background.
Momma and Daddy. Sometimes in jest I’ll say “my sainted Father” or if I’m being pretend-formal I’ll call him Father. He will be 80 in June but he’ll always be Daddy to me.
My bio-dad I didn’t really spend much time with. “Dad” or “Daddy”, usually, though.
My stepfather I call by his given name, or occasionally “Da”.
Geezer, Old Man, O O (just the two letters), the name that was on his actual birth certificate for 50 years before anyone noticed, his first name, manslave…really, he answers to many names. Of course, he has some pretty bad ones for me, so it evens out.
I voted Daddy though, because that is him most of the time.
Any time I addressed my father it was through this song and dance.
Was raised by my grandfather. Called him “Pop-pop” when I was a tiny tot and “Pop” when I was an adolescent. So that’s what I put.
By the time I was a teenager I called him “grandpa,” though.
I asked my parents who grew up in New England and were kids/teens in the 60s if they knew anyone who used “Pop” back then instead of “Dad” and their answers were no, unless you count Patty Duke and Dobbie Gillis.
My husband was given the nickname “Big Papa E” by the kids several years ago. That got shortened to “Papa E” and then “Pops”. So he is one dad who is called “Pops” by his kids.
