A form of measurement often used to describe the love one has for his/her spouse/boyfriend/girlfriend/etc. It is also used to describe likings to food as well.

This word is used to outdo any other form of measurement. However, it can be defeated by Mostest times infinity.

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.
