When a grown man has many temper tantrums over stupid insignificant situations such as someone not sharing a burrito with him. There names are usually michael. They have an urge to hit thinks such as lockers, walls or females. Their tantrums usually last for about 30 min to a day. They are lame. And if want them to get over it, then option 1: leave them alone, option 2: call them mr. pissy pants in a cookie monster voice. Or just leave them alone or deal with the beatings, and expect bruises.
mr pissy pants: can i have some of your burrito other person: no
Mr pissy pants: *blank angry look
other person: AWWWW MR. PISSY PANTS!!!! hahahah
