irrational impulse

[StevernBeaus]

a strong spontaneous and irrational motivation

[Dave Paprocki]

An irrational impulse refers to a sudden, involuntary desire or inclination to engage in a behavior or action without rational judgment, logical reasoning or conscious decision-making. This is usually driven by emotions, desires, or psychological factors rather than objective or logical thought. These impulses may often be seen as illogical, unreasonable, or inappropriate in the given context.
