A silly, ridiculous rendition of the word "Most", used to beat a friend in a competition to see who "____" the most ("___" being the subject being argued.)
Leslie: I HATE YOU
Ice: I HATE YOU MOAR!
Leslie: I HATE YOU MOAST!
Ice: I HATE YOU MOASTEST!
Leslie: That's not even a word >.>

"I missed you."
"I missed you moar."
"I missed you moast."
"I missed you moastest."
