one-off 

A person you only plan to have sex with once. A one-night stand.

He's just a friend but he's cute enough that I would consider a one-off.

One in the baby maker, three in the brownie baker 

One finger (primarily a thumb) in the vagina, three fingers in the butt-hole

Dude I was so drunk and she was so horny, so I for some reason put "One in the baby maker, three in the brownie baker" - This term was originally coined in a drunk-dial voicemail to a special friend after a night of drinking and after-partying in a hot tub with a naughty french girl.

One Less Lonely Boy 

On September 5th, 2010 at his concert in Maryland, Justin Bieber got pranked by his crew. For his song "One Less Lonely Girl", he usually has a female fan from the crowd brought up on stage, and he sings to her and gives her flowers. Well, on September 5th, a old, fat man wearing a crown was brought on stage. Justin was creeped out and wouldn't even give him the flowers, so he gave them to a girl in the audience. He jokingly knocked the crown off the man's head also, when he finally realized the crew had pranked him. At the end of the song, the man picked Justin up. So what usually is known as the One Less Lonely Girl, turned into the One Less Lonely Boy that night!

Justin Bieber: *backing away from creepy old man on stage* "there's gonna be one less lonely boy...?"

one-finger salute 

Same as The Eminem salute, the freeway salute, the Jersy salute,
the finger, the bird, just to flip off the ones you really can't stand.

In other words , the middle finger.

There was many a time
That Roy Lee acted a prat.
Seriously, he was an older version
Of a poseur, a brown noser, and a really spoiled brat.

So, whether it was behind his back
Or right in his PLAIN VIEW,
I'd showed him my middle digit
And with no hesitation, too!

Though I had quit that job,
I've given him the one-finger salute...
Just to prove he's a big loser...
AND to piss him off, to boot!

One Eyed 

Only seeing in one direction.
Oblivious to other views and opinions.
Pirate...

Person 1: Homosexuality is wrong!
Person 2: But they've found love, surely if two people find...
Person 1: (Interrupts) IT'S WRONG!
