exploding offer
n.— «So how do judges compete with one another to attract top law students? The most favored method is the pre-emptive strike, or “exploding offer.”…By interviewing and making offers to students just a few days earlier than her colleagues and making a take-it-or-leave-it offer to the best interviewees—under which the chosen students must decide whether to accept the offer within a very short time frame, or even on the spot—a judge can ensure that she, rather than another judge, gets her first choice of law clerks.» —“Federal judges go to extremes to select law clerks” by Michael C.
