Flumtastic is a word first used by Keiichi Tsuchiya, better known as the Drift King (Not to be confused by K-Brown the illegal street racing Drift King) and his friends from the Canadian underground rap group, F.L.U.M. Flowing Like Ultimate Mcs. The word varies in meaning but the general concensus is that it refers to someone or something that expels greatness and excellence while making those around the subject fall flat like pathetic underachievers that should be out on the streets begging for money to buy more alcohol to drown out the sorrows of their worthless existence like a bum (aka Bumtastic). Fans of F.L.U.M. have added on to the definition by mentioning that if you're "Flumtastic" then you are almost as good as the members of F.L.U.M.
Example 1: Damn, girl! You lookin' flumtastic right now! Don't blame me if you end up in a bed covered with rose petals.
Example 2: Drop a couple of flumtastic bars, dawg! Why don't you spit a hot 16 for the hood, homie?
Example 3 (From the freestyle MC Without A Conscience by OG Paperboy): My squad keepin' it flumtastic/ None of that "put you on blast" shit/ Just prepare to get your ass kicked and thats it/
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
Person 1: Damn, Dustin already has a new girlfriend?! It's only been two weeks since he broke up with his fiance! I think he's a sociopath.
