A descriptive term of art for the act of making a fantasy football draft pick two to three rounds ahead of the general consensus of where that pick should actually be slotted. This action is usually coupled with an immediate sense that the draftor has somehow scooped the rest of the owners of the league. A Slebosian pick historically results in the absolute ruin of an owner's fantasy football season.
Drafting Addai in the third round of his rookie year was postively slebosian. I slebosed the fifth round when I chose Eli.
