Spelling Defisit disorder,

SDT

a group of rotund and hopelessly socially inadequate girls who lack any kind of redeeming qualities whatsoever. Their enlarged stomachs, legs, thighs, butts, and multiple chins allow them to completely engulf an adult elephant in mere seconds. It has been recently discovered that each SDT possesses a gravitational pull comparable to that of the moon due to both objects' comparable masses.

I would rather eat glass than hang out with an SDT. If you want to experience nausea, stare at an SDT for a few seconds. An SDT has more cellulite than Margarat Thatcher on her worst day. It is possible to take body-shots out of the ripples in an SDT's fat ass.
