statistically significant other 

A significant other whose status is not created by a agreed-upon relationship status but by how much time is spent with them. Could also be considered a behavioral significant other.

Combination of "statistically significant" and "significant other."

Statistical Mechanics

The belief that thermodynamic systems can be expressed using statistics. It is mostly used to more accurately express a system where there are many microstates involving microscopically observable quantities (e.g. kinetic energy of particle 1, 2, 3, ... , n-1, n or Potential energy of particle 1, 2, 3, ..., n-1, n as opposed to quantities like pressure or volume).

What the author of this article should be revising now, Statistical Mechanics (or stat mech as it's more conveniently known) can be described by many physics students as a "cluster-fuck of endless equations and probability distribution functions designed to intentionally screw up their mind altogether".

It is widely known that stat mech is utterly incomprehensible until the actual exam day, when all the nonsensical examples and equations (most notably finding the entropy of an elastic band expressed as a function of the number of links in said band, and the expression of gas molecules as masses on springs) seem to reach perfect clarity and they tend to walk out with at least a 2-1.

"You going to statistical mechanics?"
"No fucking way, I'm making noodles for lunch!"

sadistic 

1. To derive pleasure or enjoyment from another's pain. Whether physical or emotional.

2. Extreme cruelty.

Celisse: Oh, you're right. There are also the times where I humiliated you, crushed you, made you cry, made you want to die... If you consider those to be different than just soundly defeating you, I suppose I stand corrected.

Jolt: Celly...you're so cruel to me! Please stop! You're so sadistic!

Celisse: HAHAHA, I know Joltykins. But I'm not stopping anytime soon.

Jolt: *cries*

Sadistic tickling 

The act of performing prolonged and relentless Tickle Torture to a typically bound and helpless victim. The intense torture is focused on an area of the body highly sensitive to tickling, often the soles of feet, with the purpose being simply to torment the victim with cruel and unbearable Tickling.

Person A: "So you taught your sister a lesson last night?"
Person B: "Yeah, She's super ticklish, so I punished her with Sadistic tickling. After a night of that torture, she won't be trying anything like that again."
