Man1 : "Damn.. She's so thicc.."
Man2 : "Her?- dude I think you're Thiccblind"
Man1 : "No I am not!"

When someone believes a person who is thicc isn't thicc and someone who is not thicc IS thicc.

They might deny it but they're really thiccblind.
Man1 : "Woah, she's so goddamn thicc.."
Man2 : "Her? Dude I think you're thiccblind."
Man1 : "No I'm not."
