A reference to a man's penis being bigger than normal.
Woman 1: Did you hear about Mike and Ashley?
Woman 2: Yeah! I heard he was packing, but she said it was really big, like Phallacy BIG.
It is a lie that all who believes in it gets fucked over
Phallacy is used in the same context as fallacy. it is a play on words. examples are believing that you will be happier being poor, believing that your GF isn't cheating on you, the media doesn't lie
Phallacy: the false belief that one has a large penis
Mike was talking shit swinging his dick around like he's working with something massive. It's a total phallacy, he's hung like a squirrel!
