Cuff Scuff 

The unfortunate second wipe scenario, especially prominent in the office workplace, resulting in a smudge on your shirt cuff. Particularly likely after a hot curry the night before.

Just went down for a shit but arse gravy was the order of the day. Got a rather embarrassing cuff scuff as a memento.

Padme’s Snuff Box

Is the art of Inhaling Weed (any device and type) and blowing it into a CPAP machine. Once in the machine blocking the exit while breathing normally through the mask.

It was developed during an intense research session, with participants laughing at the poor guy who uses a CPAP to sleep. The participants called it a Darth Vader mask, thus the procedure was named.

Mike wished he had a CPAP machine now, so he can pull of the Padme’s Snuff Box.

Heel scuff 

Having to shit so bad, you're about to shit yourself. So you clench your ass shut and try to walk until you get to a toilet to relieve yourself.

I had to shit so bad, I heel scuffed down the hallway till I found a restroom!
