When a man wrongly believes that his penis is much larger than is actually is, he is living.
I was with this guy last night who listed "well endowed" on his Tinder profile. Maybe if he was comparing it to his pinkie finger. Girl, that dude is experiencing a phallusy fallacy.
1: Dude did you see John punch that guy in the throat?
2: Yeah, but he had it coming, he dissed John's mom.
1: Hmm, that's true. I guess John committed a logical phallusy.
