->"Oh, and stay away from your friend the Captain. [[RescueRomance You save his life, he saves yours,]] this leads to that... ''[meaningful pause]'' I was young once too."
-->'''Dr. Sid''', ''Anime/FinalFantasyTheSpiritsWithin''

The pattern is always the same: [[RuleOfThree Two minor, innocuous incidents]], and then the whammy: "...and the [[NextThingTheyKnew next thing I knew]], we were having sex."

The most popular way to brag, to confess to someone you've cheated on, or to answer an angry parent who has asked, "How did this happen?", as a way to avoid [[TooMuchInformation going into all the details no one really wants to know]]. If this is how someone (optimistically) ''plans'' to get someone into bed, it's a MissingStepsPlan - Step One, BoyMeetsGirl; Step Two: [[NoodleIncident ???]]; Step Three: CoitusEnsues!

One thing led to another...and the United States dropped two atomic bombs on the sovereign nation of Japan." "This is ''some pamphlet!"''
