Why do other players call Jason Demers "Daddy"?

If you follow any of the San Jose Sharks players who are active on Twitter, you've probably seen something like this:

@jasondemers5 @TJGaliardi the single life eh daddy. That's why you got me #bromancecity

— Logan Couture (@Logancouture) May 12, 2013

Logan Couture, Brent Burns, TJ Galiardi, and others all have a habit of referring to Jason Demers with the nickname "Daddy."

Obviously, this is very strange, and it has bothered me since I first noticed it was a thing.

Recently, I decided to try and get to the bottom of the Daddy mystery:

Jason Demers' nickname among the other Sharks is "Daddy." This is a true fact we can ignore no longer.

Back in May I started to pester Demers and other folks on Twitter, repeatedly asking them to explain the nickname:

. @Burnzie88 hey Brent do you know why the other players call Demers "Daddy"? People are really curious.

Hey @macklemore can you ask Jason Demers why the other players call him "Daddy"? @jasondemers5

And then, finally, I got my answer.
