Remember in the movie City Slickers when our favorite cowboy is about to find out the meaning of life but then the one with the knowledge to pass on about what the "one thing is" keels over first? That's how finding the One is. You die before you find out who it is. Or die trying! Or try not to die?
Is the One an actual thing? Are there multiple ones? Is there one for now and one for later?
When you are about in your early teenage years, you'll be scrolling through google, looking at whatever the fuck you looked up. Then, after a lot of scrolling, you see it. It, being the one picture that transmits a sexual feeling. You decide to look deeper into the internet, using rule 34 sites and such.
Essentially, it's the one picture that turns you on and makes you want to masturbate for the first time.
Person 1: Hey, you remember when you first started masturbating?
Person 2: Yeah, I saw That One Image and it totally set me off...
