I think the embaressing pics are usually posted by teenage girls, or older chicks trying to be teenage girls.
For a guy.. when he hangs his nuts out in an “embaressing” pic – its not that embaressing. He and all his friends laugh and thinks its cool, and there is very little shame in it, but its expected that guys get up to such shananigans.
BTW.. hanging your nuts out in the photo sneakily, is known as “sneaky nuts”
