male menopause
Typified by mood swings and irritability, lack of sex drive, tendency to go home and bake rather than go dipping the wick with the wife. "Male menopause" may be the result of hypogonadism, where the testes produce few or no hormones. Kind of lame for all involved.
"Dan's male menopause is worse than usual today, just found him weeping in the break room, eating his second Kit Kat chunky for the day, and it's not even 10am."
