Gambling term, Bankroll Management. Usually refers to poker.

Proper bankroll management would be playing within your limits so you can withstand tough losses and bad beats. Unproper bankroll management would be putting a high percentage of your bankroll on the table at one time.

Brms, or Bridgewater-Raritan Middle School located in Bridgewater, New Jersey, is the hell of all middle schools. The school was built way too long ago and doesn’t have a/c in over half the building, as well as some broken ass heaters which spit out cold air during the winter. At the Ghetto that is Brms, teachers like the, self proclaimed, “Jamindian” (Jamaican-Indian) Mr Maragah, and hippie Mr. Marton can be found. If are just going into Brms this year, good luck, you’ll need it.
