The act of sitting on a woman's twat and taking a long, stiff, preferably brown stool directly into her vagina until she orgasms.

When two women use a turd as a double sided dildo.

When 5 or more black men get in a close circle and stack all of their penises on top of one another, similar to the kids toy.

No, No, No! You're all wrong. A Lincoln Log is when you drop a loaf that's so big and solid that it by itself (without any t.p.) can plug the toilet. if the toilet doesnt plug then it's not a Lincoln Log. Officially it has to be one of those high pressure flushing public bathroom toilets for it to be a real Lincoln Log. You know, those toilets that flush with the sound of a jet taking off. Ever since my good friend Big Head Ed introduced eating regular fiber in his diet nobody has been able to create real Lincoln Logs, so out of traditional honour the standard has dropped to any type of toilet. And please people, lets capitalize the words Lincoln Log. Show some respect for its glory!

The beaded turds that hurt to push out and remind you of something you found in your Mom's dresser once

big old turds, so solid you could stack them.

A fantastic toy. Has been in existance for at least 50 years. Vaguely reminiscent of Legos, but made of wood instead of the cheap, brightly-colored plastic that so dominates the toy market today. These pieces of wood were round, and maybe a foot long, and were notched, such that you could build a real log cabin, but one that would fit in a corner of your room. All you had to do was make a square with 4 logs and line up the little notches, with the left and right sides under the top and bottom sides (or the other way around). Then add two more logs. And two more. Repeat until your cabin was as tall as you wanted it to be. A very simple process, but it was really cool. It also had some sort of a roof, though I don't remember exactly how that worked; I just remember the roof was green.
