¡¿What the foci?! is an expression that is relatively unknown and unused, considering that each year millions of high school students worldwide experience a great need for such a phrase. This phrase is simultaneously a profane question and exclamation, and so a fukquestatement. Within the realm of high school mathematics, a "focus" is a point within the interior of an "ellipse" (a circle that stayed out too late the night before, i.e. ellipsicated). An ellipse is one of the conic sections aka connexations sic. In fact, there are two such points, and the plural is foci (as in octupus / octupi). Students are often asked to find the foci of an ellipse in a homework problem or on a test. Typically, this situation arises in the spring of the school year for students in Algebra 2.
