Define Stay at Home Parent?

Can you please help me? What is a stay at Home Parent? Can you still have your kids in Daycare even part time and me a stay at home parent? I was reading about a daddy that was telling the world how he was a stay at home father in his Christmas Card. I thought cool for him someone I know I could talk with about Stay at home issues. I emailed him and we started talking, He maybe has the kids 3 to 4 hours by himself. He still takes the kids to daycare everyday. So does he work? Go to school, maybe remodel the house? NOPE, he uses that time to get stuff done!! Like what? Would I love to have a few hours alone each day? Sure and often when the wife and son go to bed I get this. The question is? Is this a stay at home parent? Why does this piss me off?

The look!!

 Every Mr Dad has gotten that Look, Even more so when your 6'2 -315 pounds and bald and look more like a cop or a PE teacher rather then a stay at home Mother- Girl you may be cute,  but I'm not here  to hit on you or go on a date, I'm here to allow my 15 month old son to play with others because its 20 degrees out and 13 inches of snow outside, I'm running out of things to do at home. So don't be scared I'm married and plus your not my type-

Taking a break for yourself-

This might have been the hardest part of being Mr Mom to this point. I have been battling a cold bug of something and a huge list of baby proofing the house along with some maintenance thst as good of a father I can be I can't seem to get them done.. My wife has been trying to get back to see her father and Grandma for are son. My wife came to me with the idea, how about you stay home rest, recover have fun for you. One might first thing HELL YEA- Party, Strippers- beer-pizza and more strippers. My 1st thought is what if DJ gets sick- are som has the strong stubborn head of both his parents when makes for some fun times. He is the best thing to happen to me and my wife, however I want control. To be there for my son and my wife. I hate the feeling of not having control. HOWEVER Its not fair no my son that daddy doesn't take care of his daddy. This can be mental and health- But for me to be a better husband and father I need to take time for me to better my family.

How did I ended up a Mr Mom

Well- My son got sick from daycare an couldn't go so my Job a daycare fired me
