A history or alternate history fan who is firmly entrenched in the belief that the Confederate States of America should have or even did win the American Civil War. Leeaboos are obsessed with an alternative history that "could have been" and do not like historical facts getting in the way of their militaristic fantasies. Many feverently believe in Northern Aggression, the Lost Cause of the South, the Myth of the Black Confederate which is the retroactive conscription of dead black Union soldiers and slaves into the CSA army.

Based on the similar-sounding term "weeaboo" (a catch-all definition for Japanophiles).
Oh good another Leeaboo is here to whitesplain how slaves loved their master so much that they took bullets for them...

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
