Not the UFO but you were closest. Let's run it through.
Whites v Blues
Blue player tripped on half way. Ball rolls to a team mate who controls and looks up and sees 2 players on the overlap, and then takes another touch. The touch is heavy enough to make it run away from her, but not strong enough to make either of the overlap. She then appeals for the free kick,but I say it's too late and she's duffed it up, and the whites go down and score a worldy.
The serious points:
1: For me, she's wasted the advantage by messing up the second touch, she's had time on the ball. Management and team mates disagreed naturally, but what do you consider to be advantage
wasted?
2: a) 99 times out of a hundred this will not lead to a goal, but although I believe I'm right in law, in terms of the game I was stuffed (for that half anyway). Things like this can happen to all of us - it's how you react that is the measure of you. You could let it go to your head and you spend the rest of the game on the defensive - or you can decide to stamp on things straight away from there on an be on top of it all. Match control and feedback from the players on both sides much more positive in my case for doing just this. (I'll still get a 61 from the blue coach however but that's another story, something to do with a 1-0 defeat
)
b) Sods law says had I blown straight away the overlap would have come off immediately and I'd have had an earful from the bench for that.
3: Don't play advantage on halfway or close to the dugouts!
