When I was younger, kids immy group would brag about being the biggest . How they were as large as trees; and thick as fire hydrants. To my knowledge no one ever took them seriously. If I remember correctly the best reply when someone said he was bigger than you was " we should ask your GF " This immediately shut down the bragger
But we were young and stupid. Should this still be the topic of conversation decades later; and being made by alleged responsible adults, I would think that I would need a better / new crowd of friends
