Invertible

In linear algebra, an n-by-n square matrix A is called invertible (also nonsingular or nondegenerate) if there exists an n-by-n square matrix B such that:

AB = BA = I (where I is the Identity Matrix).

Otherwise, in life, it refers to the case where something can be transformed into something else and transformed back.

Randy: Sally is so invertible; real marriage material.

Sandy: I know, nonsingularly so. Put a few drinks in her and you can get her on her back and yet in the morning she still gets up and cooks you breakfast.

inertia

Simple terms: The 'reason' that to why you have to use some sort of effort to move or stop something like an object.

The law/principle of inertia states that a body at rest will remain at rest and a body in motion will continue moving with a constant velocity unless acted upon by an external non zero force.

Don't confuse this with momentum

Due to inertia, a moving body in space (ie a vacuum) will not stop or deviate unless another non zero force acts on it (eg gravity)

Invertagina

1. When a girl pulls her labia outwards to their full extension, and then places them into a penis pump. She will then pump until she can pump no longer, at which point she will double tie(or as many as needed) a rubber band around the lips forming a structure similar in shape to a limp penis.

2.It is the antonym of a mangina

Cindy fucks Steve's mangina with her invertagina thus allowing neither of them to get off.

Homework Inertia 

The amount of effort it takes to get started on your homework.

Jim has a lot of Homework Inertia, he took until 11:00 PM to care about getting started on it.

invertigate 

(adj.) characterized by an occasionally capricious disposition that undermines a prominent topic in an ongoing dialogue by redirecting conversation on the pretense of remarking on external visual stimuli.

Her remark on the scenery was no mere fleeting observation, but rather the mark of one skilled in tactically invertigate persiflage to move the discussion in another direction.
