UPK 

Stands for Ugly People Kissing. An instance of witnessing two ugly people making out or otherwise engaging in a PDA in public.

I was on the subway today and I saw two mutants getting busy with some seriously wrong UPK action. Luckily I had just gotten some take-out so I was able to use the plastic spoon to gouge out my eyes. Jebus, guys, leave that shit at home!

Upknuck 

The single most positive affirmation between friends, colleagues, what have you. Said affirmation carries more weight than even those of normal knucks, secret hand shakes, high fives, etc. An Upknuck is preformed when two, or more, people bump fists with metacarpals facing toward other participant and phalanges facing up towards the sky. "Turn that pound upside down."

Rules to Upknuck:
1. You don't deny an Upknuck at any point one is offered. Said denial of Upknuck can result in said Upknucker refusing any further Upknuck related offers to said Upknuckee with Upknucker being completely justified.
2. You don't blow up an Upknuck. Ever.

Dude 1: "Just got a rim job from Sally!"
Bro 2: "Upknucks, brooooo!"

Blump-Upkin 

Combination of a Blumpkin and an Upperdecker.

The act of receiving a blow job while taking a shit in the upper section of a toilet after taking the lid off.

After becoming bored with the typical Tuesday night Blumpkin, Andrej decided to spice it up a bit with the Blump-Upkin. Tuesday nights will never be the same!

The Scottish equivalent to "upskirt", but they wear kilts, not skirts.
