Slider up 

A type of BASE jumping requiring little to no skill but high risk where participants climb up very high antennas (usually around 900’) and jump off taking a slider down delay. This aspect of BASE jumping is usually performed by people lacking basic knowledge and ability to not piss themselves when jumping slider down.

Cockstick: Hey you want to go BASE jump tonight?

Badass: yea man I know a sweet slider down B we can hit.

Cockstick: that sounds way to scary for me I was thinking slider up with a 3-4min canopy ride....

Up and Down The Slide 

Wanna Fuck?, Let's have sex.

Another term for fucking. If you want a guy to know that you want to fuck him, say this phrase and he'll understand you. Either that or lick your lips...

Oh, and if your guy doesn't understand this little phrase, he's on crack and he's lost his marbles!!! But...try to explain it to him.

Girl: "Hey baby."

Guy: "Hey, what do you want to do today?"

Girl: "I wanna go up and down the slide. Can we?"

Guy: "Sure, let's go!"

Upper East Sider 

Also known as UES. Term is mostly known from the CW series Gossip Girl. The UES is mostly well known for being far more “superior” than the Upper West Side (UWS). The UES however, in literal and metaphorical term is where the most wealthy, famous, and over privileged Manhattan citizens mostly live.

Gossip Girl: hey upper east siders, Gossip Girl here.. And I have the biggest news ever.

Upside down spider 

An undefinable phase which can pertain to anything in your vast imagination.

You're about as cool as an upside down spider.

I'd rather suck my own poop than eat an upside down spider.

Upper West Sider 

upper west siders live in rent controlled apartments that they brag about paying $350/month for. They are the cheapest, most inconsiderate, self-righteous people walking around, in addition to the sense of entitlement that they harbor.

That Fucking Upper West Sider has a huge sense of entitlement, plus she didn't pick up her dog's shit from the middle of the sidewalk!
