The dad-stache is a unique moustache that is perhaps the pinnacle of all staches. While it appears similar to a 70s porn stache, it is not quite the same since it is not as creepy.

Males can only grow one of these badboys once they have had a kid (in particular a son). It is a biologic reaction that has evolved through the years because such a moustache commands respect from ones offspring and in general demonstrates clear bad-assery.
You kind of had this nasty scum stache vibe going on until your wife had your son. Then all the sudden you developed a wicked dad-stache that made Burt Reynolds look like a pubescent cheeseball!
