Mostest-Ostest 

The largest real number imaginable. It is equivalent to infinity -1.

Generally used in disputes to quantify how much one likes/dislikes something.

(Guy) This burger is awesome. I love burgers.

(Girl) I love them more than you, I love burgers the most.

(Guy) I love burgers the Mostest-Ostest.

(Girl) Your mathematical superiority has left me with no viable response. I bow down to your supreme love of burgers.

Mostestestest

Something that is more than most. More than mostest, too (because apparently that's in some dictionaries).

Maddy: I love you, Hannah.
Hannah: I love you too!
Maddy: I love you more!
Hannah: But, I love you most...
Maddy: I love you mostest, though.
Hannah: I LOVE YOU MOSTESTESTEST.

As well as physics, it is said when one attempts to expresses the mostestestestestest genuine, realest, and deepest affection.
