throw a wobbly/wobbler
- verb to suddenly behave irrationally or to have a temper tantrum. This phrase has become popular in Britain since the end of the 1970s, but dates from the 1950s. Its exact derivation is unclear, but may reflect simply an attack of shaking or quivering, or alternatively refer to throwing or bowling a ball in an erratic and confusing arc, or may refer to the loss of control when a wobbling wheel comes off e.g. a wagon or a bicycle.
