(or branding) The intentional act of 'accidentally' marking someone during sex in order for their partner to find out about it and bring an end to that relationship. Scratching, pinching, biting, spanking marks, bruises or cuts, especially in areas like the buttocks, genitalia or breasts.
After seeing this girl on the side I got out of the shower and I was a bit pissed and hadn't realised she'd branded me with scratches on my back! When my girlfriend
clocked it she went nuts but the other girl's wanted me to break up with my girlfriend
for a while.
