The act of platonically or semi-platonicly sleeping with another man.

Not uncommon at the time, Abraham Lincoln would often sleep in the same bed with other men during his time practicing law in Illinois. Hence sleeping "lincoln style" or "lincolning up" is adopting a male bedfellow for the sake of convenience, or necessity. While the arrangement is assumed platonic, nothing is certain once the lights go out.

Also known as lincolning up
Since we accidentally booked a hotel room with only one bed, tonight me and Bob are sleeping lincoln style.
