Dropping a "Jefferson" is when you go number 2, poop, crap, deuce, drop the kids off at the pool, etc.
Thomas Jefferson is on the $2 bill. When you "take or drop a Jefferson, you are going number 2". It is a nicer, more educated sounding way of taking a crap.
"You all hike on ahead....I'm going behind this large live oak tree to drop a Jefferson."
Setting: School library
Teacher: "Where's Johnny?"
Student: "Mrs. B., you know that he can't spend more than 10 minutes in here without having to take a Jefferson."
