A portmanteau of 'Man' and 'Tantrum' that describes a man losing his temper. The term is inherently derogatory as the term 'tantrum' is most often used to describe an irrational or selfish anger, typical of infants. The term is often used by those who wish to undermine someone of the opposite gender by use of a sexist remark, analogous to a man claiming that a woman is "on her period" or "having their time of the month" when they are distressed.

A "Mantrum" can be described as a display of uncontrolled emotions, particularly anger or frustration, exhibited by an immature adult male.
It resembles the temper tantrums of a small child, characterised by outbursts, shouting, crying, and often dramatic gestures.
This behaviour reflects an inability to manage emotions and cope with challenging situations in an adult manner, resulting in a scene that feels both childish and disruptive.
Simple description: Typically an immature adult male displaying an uncontrolled outburst of anger and frustration, similarly like a young child would.
