Mutual masturbation involving at least two, usually three or more men, done for either pleasure or orgasm. Typically done sitting or standing with each man involved stimulating at least one other man in the group, hence the plural "noodles". Similar to a circle jerk or other group masturbation, but with no one only masturbating them self, and all the parties being male.
Guy #1: How was your date last night? You two hook up?
Guy #2: Even better! We had dinner at an Italian restaurant. Then afterwords he and I picked up the waiter and we all went home and whacked each other off!
Guy #1: Wow, nice job! Tossing the noodles is a blast!
A Cup O' Noodles occurs when doggy style sex is going down and the male pulls out his penis and cums in his cupped hand. once his female coutnerpart turns around to see why the fun has stopped, the 'cupped' hand of semen is tossed in her face.
It is appropriate for the male to then scream 'CUP O' NOODLES IN YO FACE!'
Tom was enjoying some back door action with Sally. Prior to climax, Tom decided Sally's snooty attitude at the bar and the amount of time it took to bed her called for a sturdy 'cup o' Noodles.'
Taking great care and positioning his hand just right, Thomas released his member from her love muff, held onto the bedside table for support and awaited Sally's head to turn.
'What's up baby, why'd u...'
With a flash and a flick of the wrist, 'CUP O' NOODLES IN YO FACE!,' Tom Exclaims.
Sally did not return Tom's calls until later that month.
