When Chase and I are arguing and I make a ridiculously good point and he says, "Bullshit" and I say, "Bull-true" which is a cross between saying what he thought was bullshit was actually a true statement.
From the movie "Stand by me"

Chris: "Gordy, you're a good writer, and someone needs to encourage you to write, and if your parents are too fucked up to do it, then maybe I should"
Gordy: Bullshit
Chris: Bull-true

2) It is used to define a feat or a deed that is nearly impossible to achieve.

3) It is the opposite of "Bullshit" or BS.
4) Does not involve BS,luck. Involves true courage.
5) In the Halo game, you earn a Bulltrue batch when you take out an enemy who is charging at you with one of the most deadliest weapons in the game - Energy Sword.
