partylining 

When someone shares the same plane of movement with you in a paralell manner, usually very annoying. Happens mostly while driving, when one drives next to you, speeding up as you speed up and slowing down when you slow down, preventing you from changing lanes. Also happens while walking down the street, waiting in line, or jogging somewhere populated.

I was gonna get off at the last exit but that motherfucker in Tauras kept partylining me so I couldn't get over.

Hey I think that guy in the blue shorts has something for me. Everytime I get up to run a lap he keeps catching up and partylining me. It's really uncomfortable!

Partaining

"Yeah I Partained him hard, 152 to 49." -Guy 2
"That's crazy, he's so terrible." -Guy 1
"...I also had intercourse with his mother." -Guy 2

Partyjoining

The act of overzealously agreeing to do things with friends and acquaintances during a party or other social gathering despite the fact that ordinarily you would have no interest in doing so. Often followed by flaking out and not following through with the plan.

Able agreed to go to the Museum of Modern Art with Betty and Charles, but he was really just partyjoining.

pantylining 

When a male grazes his fingers across the bottom of a female's stomach, about where the elastic of her panty usually is, causing her to become extremely turned on; usually a precursor to being fingered and possibly sex.

Girl 1: Last night my boyfriend tried pantylining me.
Girl 2: How was it?
Girl 1: I've never been so turned on in my life!

Paralining 

A sport in which a trampoline floats towards the ground at 20,000 feet, suspended by four or more parachutes, and a skydiver jumps up and down on the trampoline without his parachute deployed. When the trampoline gets low enough, the skydiver jumps off and deploys his parachute for a safe landing.

Parachuting + Trampolining = Paralining

Guy 1: dude I went skydiving this weekend its was so sick!! what an adrenaline rush!!!

Guy 2: F that man I just went paralining

Guy 1: wtf is that
