Younger Brother

of Brother(s)


Younger or Youngest Brothers of Brothers are somewhat impulsive souls who are more inclined to seek a thrilling adventure than other types. Y-BOBs are more likely to try skydiving, own a motorcycle, backpack Europe or join the military than their more conservative bigger brother(s).

Their heightened creativity and relaxed demeanor set Y-BOBs apart from the pack. Most women love these men. And why not? They're outgoing, charming, entertaining and generally agreeable. However he tends to not to be very romantic, and doesn't coddle his mate with emotional outpourings of affection - preferring to be lighthearted and focused on excitement, rather than gushing.

Most Y-BOBs display the (P)erceiving Jungian Temperament. They typically are not the detail oriented task-masters that their Biggest Brother is; unless he is a *Challenging Second Born.
