Top definition

When you try to do something in "one fell swoop" (Shakespeare defines this as "in one fluid motion") but end up falling and landing directly on your face.
You tried to throw the winning touchdown fluidly in one fell swoop, but you fell on your face in one fellstoop instead. Good work, Matt Stafford.
