kick in the (seat of the) pants, a

A reproof or reprimand; also, a goad or spur to get someone moving. Both can be literal or figurative. The idea must be very old indeed, and the expression, a euphemism for a kick in the posterior, appeared in Samuel Butler’s Hudibras (1663). A more recent term with the same meaning as the first sense is a kick in the teeth, used from the mid-twentieth century on.
