Flicker Gooning is an extremely difficult variation of gooning where a gooner brings themselves to "point of no return" before letting go of their penis with and holding back the ensuing explosion by flexing the same muscle that allows you to make your penis "jump." It is extremely hard to keep a consistent contraction in this muscle, so a "flickering" technique of repeatedly stimulating the muscle is often employed.
" You're 8 hour goon sesh doesn't impress me. I can flicker goon for 7 seconds!"
