In the same way your normal slut meanders from one person to the next with no real ties, an intellectual slut may drift from one idea or principle to another, with no proper platform.
The obvious implications of this are that the slut in question will have only a rudimentary understanding of the finer (technical) points of the concepts. To paraphrase Truman Capote, they will be typing instead of writing.
On the the other hand, the slut is less likely to develop a rigid mode of thought, dogma, or any other such mental phalanx.
By the time they are done with college, most sluts will have given up on sophism, and try to settle down with a nice 10 point worldview. There are those however that may continue on to become intellectual whores.
