dad fact

That weird random bit of information that a Dad will suddenly drop on you after you ask a fairly simple question. And is almost always 100% correct.

Me: why do international pilots need to know English?

Dad: It is actually called Aviation English. It was implemented because of a really bad plane crash back in the 1970's caused partly by language issues.
Me: *Googles it, sees hes correct* that's a Dad Fact!

An unfounded but logical piece of information that may or may not be a fact, often wielded by dads at a BBQ.

Trav: "Did you know that if you pour Sprite on your balls you can taste it?"

Mike: "Sounds like a dad fact"
