Mostest: To love someone more than anything that exists or has ever existed. This is more than most and cannot be beaten, under any circumstances, especially by the non-existent words "mostestest" and "mostestestest"
Nereyda: I love you.

Nereyda: Nooooo. I must accept my defeat. You really do love me mostest baby

Even more than most. The maximum amount of anything. Many believe it to not be a word, but it still means a lot.
Girl: I love you more.
Boy: I love you most.
Girl: I love you mostest.
Boy: That's not even a word!!!
Girl: It is if I say it is!
