When you successfully remove a bra in one attempt.
Derived from the word "Yahtzee", the word yelled when you win at Yahtzee.
Men commonly struggle with the removal of brassieres, so when the brassiere is removed in one swift motion, you may shout a well-deserved, "BRAHTZEE!"
Useful for frat guys bragging about getting laid, commonly followed by a high-five.
*man removes bra in one try* "BRAHTZEE!"
"Last night I banged that chick, Sandi Dougan, and I got a total brahtzee!" *high five*
