I’ve discovered it starts early in life. Boys admiring each others toys. One boy gets something new. The rest of the group circles around the new object like vultures zooming in on their prey. They have to touch it, try it out, have contests with one another to see who is the best. This apparently stays with them throughout their lives and as they get older, just turns into bigger, more expensive toys like motorcycles, cars, golf clubs, flat screen tv’s to show off to their buddies. Weird.
