Hissy fits are a type of emotional outburst characterized by intense anger and frustration. They are often referred to as TANTRUMS, SNITS, or TIRADES. A tantrum is an uncontrolled outburst of anger and frustration, usually seen in young children. A snit is a fit of temper or pique, usually lasting for a short period of time. A tirade is a long and vehement speech, usually full of criticism or accusations. All three terms can be used to describe a hissy fit.
