dadsplaining
Any time a dad starts a sentence with 'When I was your age' or 'I'll tell you why that is', and you know he’s about to drop a bunch of useless facts on you.
He says, 'When I was your age, I could spell that in my sleep.'
He says, 'I'll tell you why that is, and you’ll be dumb for the rest of your life.'
He says, 'If you were smart, here's what you'd do... and you're not smart.'
