Proof of purchase 

The somewhat fishy smell left on your fingers after fingering a girl. It can prove to your buddy you hooked up with a girl.

"You want your proof of purchase *sniff*? THERE's your proof of purchase."

virtue-purchase 

Similar to virtue signalling but done by means of buying trendy goods or services so as to display one's sense of contrived self-superiority: items such as books by politically correct authors, garish artwork purported to save rain-forests, or FairTrade coffee that makes the buyer feel woke; faddishly leftist buying habits that conform to intersectionality and other expressions of socially popular SJW pseudoscience, especially popular among university students.

Asheleigh-Meghan isn't going to actually read Michelle Obama's new book. She just bought it to put on the coffee table in case one of her black classmates shows up unexpectedly. It's more of a virtue-purchase.

And then a hobo walked out, burst into flames, and gave me a free refrigerator with a purchase of five dollars or more 

What you say at the end of a lame story, or during an awkward silence. Can be used instead of "and then I found 20 dollars" or "and that's why you never milk an ostrich"

Alana: So... I was walking yesterday, and I saw a llama. He looked at me, and then he fell asleep. So I went home because I was tired. And then I went to sleep. When I woke up it was 7:00 so I went to school

Amy:...

horny purchase 

when you buy something (pair of expensive boxers/lingerie set etc) whilst slightly aroused then you regret it after losing your arousal and thinking why the hell did i buy those?

the item then becomes relevant again next time you’re horny, but loses it’s relevance again after.

single people are 10x more likely to make a horny purchase, as you have to then (even slightly) regret the item given that nobody is there to appreciate it but you.

“why did you buy them expensive boxers, you’re single it’s not like anybody is going to appreciate them? “
“was a horny purchase mate”

SUNY Purchase 

A college set in a small town. Close to white plains, right by Manhattanville. Student body consists of musician, dancers, actors, cokeheads, pot heads, alcoholics, film makers and other random majors. Filled with inner city kids. Most of the students are "artists" and try to dress as oddly as possible to express their inner creativity. 50% gay and about 80% bisexual. This college has state troopers whose job it is to ruin as many lives as possible.

"What are you wearing tomorrow?"
"Well I was thinking about leggings, a patchwork skirt, my chuck taylors, and that shirt I got from goodwill...Wanna help me dye my hair tommorow? I was thinking Orange"
"Sure, wanna smoke in W2?"
"OK, because I go to SUNY Purchase"
