When a fellow Bro is trying to be the man and it is quickly realized he is failing. His fellow Bros can "Bro-check" him by making him chug a five hour energy. This is the practice known as "Bro-Checking".
Yoooo Scott was trying to talk big game about how many girls hes fucked at a pregame and it was a easy decision to "Bro Check" him in front of everyone.
Scott was eating hot wings last night and made it a point to tell the table he had not taken a sip of water. BRO CHECKED
Scott was at the bar last night and that bro just kept talking about how much cocaine he does. I obviously Bro Checked him.
