Little Man Syndrome
When a male of the species has less height, when standing erect, than 75% of the women in his available area and must compensate by being overtly loud or boisterous of his exploits, no matter how small. He is challenged by any other male who is even narrowly taller and feels shunned and left out when seeing other's joy from accomplishments and successful relationships with the women who turned him down.

Also known as 'small dick energy'.
