1.when someone pretends they are a few clothing sizes smaller than they are (i.e. Mariah Carey)

2. when a man thinks his cock is much larger (or smaller) than it actually is
Mariah swears she wears a size 6...her assistants replace size 12 tags with 6's to accomodate her delusional sizing

Some guys love to flash their cocks because they think it is bigger than it actually is...when people laugh, they may realize it's a case of delusional sizing
