floundered

flop stumble wallow

blunder bobble flummox fumble grope labor lurch muddle plunge pratfall snafu strive thrash toil toss travail tumble

cast about come apart at the seams drop the ball fall down foul up go at backwards go to pieces make a mess of miss one's cue screw up slip up stub one's toe trip up work at

idle laze

do well succeed
