factjamin - A factjamin is when you say something stupid and expect ever

A factjamin is when you say something stupid and expect everyone to believe it, even if it's clearly nonsense.

I told my class I can talk to ghosts. They believed me. Now they follow me everywhere.

I said I can run faster than a cheetah. I ran. I tripped. I got laughed at.

I told my girlfriend I was a billionaire. She said okay. Now she's my slave.
