D.F.I.T. = Dumpster Fire in Training. (See definition for Dumpster Fire.)
Visual example: If you were to see a teenage girl walking down the street smoking the wrong end of a cigarette, with one flip flop and one fuzzy boot, short-shorts modified to reveal her entire uterus for the world, wearing ridiculously over-sized bedazzled sunglasses, 6 colors of jacked-up make up, a cut-up wife beater top, and evidence of recent substance abuse visible from a distance...
That chick is a total dumpster fire in training!
Guy 1: "Woah... dude! Did you see that train wreck that just walked by?"
slip of the tongue perhaps,
Those idiots who drive around in a ridiculously raised pick up truck, making a top heavy vehicle even more top heavy and unstable
A:*gah*
B: "Whats the matter"
A: This dam prickup is blinding me.
B: Stupid thing's, as if there lights weren't blinding enough as it is.
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.
