Dad trolling
Making up stupid lies to your kids just because you think it's hilarious and you're too lazy to do anything else.
I told my kid the moon was made of cheese and that his dog was a space alien. He cried for 10 minutes.
I said the school was on fire and the teacher was a robot. He ran out of the house screaming.
I told my kid his math test was actually a trap by the devil. He asked for a lawyer.
