Sleeping with a girl who denies having a boyfriend, but that you later find out does have a boyfriend. The Bro-note is leaving a note for the boyfriend under the toilet seat to let him know that it happened when he takes his next piss to spare him the misery.
My friend was such a bro the other weekend. He slept with this girl that claimed she was single, but later saw a picture of her boyfriend in her appartment. He then decided to do the only thing a real bro could do in that situation, leave a bro-note. Leave a note for the poor guy under the toilet seat that only he would lift for his next piss.
