게 넘어지다

take a fall, in some way

An adverb in "-게" plus 넘어지다, "fall over, take a tumble", with the adverb carrying the whole colour: 크게 hard, 심하게 badly, 웃기게 in a funny way, 멋있게 stylishly, 이렇게/저렇게 like this. Lines cover a real fall (your roommate says she took a bad fall today), a demonstration of an opponent going down, and the figurative sense of others stumbling while you make your move. 넘어지다 is toppling over; falling from a height is 떨어지다.
