Yes "like a wet noodle" is used a lot. "Limp as a wet noodle", "moves like a wet noodle", and when actually boiling noodles I guess you are supposed to test them by throwing one against the wall---if it sticks to the wall--it is done. (I just boil the noodles for 8 minutes)"Like a wet noodle" is used also to describe someone or something who cannot stand up, either phisically or lacking in assertiveness.
