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"
Dominic: I love you.

Dominic: Nooooo. I must accept my defeat. You really do love me mostest, Steph.

A word with more meaning than more, most, moster, and mostest, Mostester is the top word to use. It can be used to describe your love for something, the amount you have, or just in everyday arguments.
