factidence
Factidence is when you're so sure about a fact, you think it can fix everything, even if it has to punch your problems in the face to do it.
'I believe this fact so much, I'm going to fight my brother for it. It's worth it.'
'No matter how hard life hits me, I trust this fact like it's my personal punching bag.'
'I'm not going to let anyone tell me this fact is wrong. I'll scream it from the rooftops if I have to.'
