Seasonal Perineum

The annual safe zone between Noddy Holder and Jools Holland

I managed to avoid being Noddied this year with that prick of a Christmas song, I'm now in the Seasonal Perineum waiting to avoid the new year's arsehole that is Jools Holland playing shit boogie woogie.

publish and perish

That awkward process of simultaneously publishing **amazing** scientific articles and realizing you still have literally zero chance at any career...ever. It is widely considered the realistic variant of the commonly known "publish or perish".

Kevin: I just published another paper in a highly reputable journal!!
Aleks: Oh...that's nice. So here is the $23.95 for the pizza...
Kevin: What about my tip!?
Aleks: Uhhh, uhhh....see you next week! **slams door**
Kevin: Gawd dammit!! I need a new job... #gradstudentproblems #pizzadeliveryproblems
--- Three hours later ---
Aleks: Poor, poor Kevin. Publish and perish, indeed...

accost the perimeter

Often done to prepare oneself to frost the perimeter, before one drops a messy pile of stool towards the hatch. Respectable men will always accost a perimeter before they frost it.

I could hear Boris accosting that perimeter for like 10 minutes before I actually heard stool splashing into the bowl!

Before perimeter is frosted, perimeter must be accosted!

Aggressive men waited outside of the communal restroom, ready to accost the perimeter one by one.

The perimeter was accosted multiple times by a large amount of guys.

The perimeter was accosted by three gang members in the public restroom.

the periscope

The act of hiding your boner between your underwear and your belly so that it faces up 180 degrees, maintaining stealth. The head of the penis sticks out of the pants but is masked by the underwear, jeans, shorts, and/or shirt emulating a periscope. Using the periscope allows you to do everyday activities, while walking around with a massive errection. (for best results use with belt)

I felt nervous to solve the math equation in front of the class, but then I just used the periscope.

I hope parents don't get the wrong idea when I am at the daycare with my raging hard-on, thank God my step-dad taught me the periscope.
