When I hear a grown ass woman call her man "Daddy", it makes me want to vomit. I envision a ho calling her pimp that. Not cute. Also it says that you have Daddy issues.
Thank you for reading.
Edit: I am not talking about when you refer to your SO as "Daddy" when talking to your kids. You are not going to tell your kid, "Hey kid, (SO's name here) wants you! Go to (SO's name here)!"
