Kill his computer before dusk, 100% guarantee he'll google it.
I checked his browser history, he hasn't googled it yet
he's acting like nothing happened now
My mom didn't care, but I dunno about your parents.
My mom is slightly less likely to care, but my dad is suspicious of my every move
I'm literally scared stuffless right now
Tell him that it's jokes about sparkly twiligt vampires
If I just bring it up when it isn't the current subject he'll get more suspicious
