Flap

A flap, or f-lap, is short for fast lap. The goal of flap time trials is to create the fastest lap time possible. Generally, all three mushrooms are used (save for a few glitches).

A flap normally begins on lap 2 (or at times even lap 3), as it is faster than starting behind the line on lap 1. A mini turbo or trick boost is generally used to start off the lap. In some tracks (Toad's Factory, for example), a flap also must start at a certain time to get optimal positions for the track's moving objects (in Toad's Factory's case, the stompers, the boxes, and the bulldozers at the end).
