One Night Stand 

A one-night stand is where two people have a sexual encounter, where there is no expectation of establishing a romantic relationship

"Last night this guy and I had an amazing night!"
"Oh really, what was his name?"
"I don't know, it was just a One Night Stand!"

one on my name 

Expression used as a goodbye among males to instruct one man to say the other man's name during climax with a girl in lieu of the girl's name. Often used among co-workers because if a man must work and cannot have intercourse, his name should still be heard among the copulating.

"Good work tonight Brian, one on my name, one on my name."
"One on my name, Jesús?"
"When you fuckin' and you pop, you say 'Jesús!' instead of your girl's name, cuz I'm workin!"

one knee pee 

n. stance taken to effectively relieve yourself, usually during an intoxicated state, in extremely crowded areas, i.e. concerts, tailgates, wet t-shirt contests, and/or food and beer festivals (when walking to the restroom is just not an option)

pee, urinate

You are at a crowded concert and the headlining act has just taken the stage. Suddenly, the urge to pee hits you! Everyone knows the lines are long in the bathroom and it will take forever. The only other option is the one knee pee. You assume the one knee stance, pull up your pants/shorts leg past the knee that is touching the ground, pull out tool and let it fly.
Warning: the one knee pee works best under cover of darkness and only in extremely crowded areas. The author of this message is not responsible for anyone who attempts to pee uphill or into the wind.

One Direction

1 - 5 twats who extremely piss off any guy whose girlfriend is a 'directioner' and makes their lives miserable while they talk about how hot Niall is or how 'cute' Zayn's eyes are and all the while make the guy seriously consider leaving.

2 - The one main flaw in a perfect girlfriend - they could be beautiful, funny, caring, and loving, which would make them perfect except they're a 'directioner', therefore dragging down their credibility.

1 - (girlfriend) omg I love One Direction and am going to see their film and Niall is the hottest creature ever and I'd almost definitely leave you if he came into my life

(boyfriend) (thinking: please fucking shut up, this is literally the last thing I want to hear, I wonder if she realises she's making me feel like shit)

2 - (person 1) Oh wow I'm jealous of your girlfriend, she's lovely and funny and insanely hot

(person 2) Yeah man I agree with you, she'd be perfect if it wasn't for the fact she's a huge directioner

(person 1) Oh shit, I feel your pain bro

one hump pump 

A woman who is so fat that when you are getting it on with her you only have to hump her once. Her fat keeps her jiggling for long enough to make it seem like you are still fucking

Man, last night I was with a one hump pump. I left after one hump and she was still shaking when I left 4 hours later!
