A combination of what is currently the third definition in bro and owned. Pronounced like those two and not like the word "brown."

A colloquial exchange which results in mass fornication-dissimilar to a Ward-Perkins which inevitably ends in dissapointment. Such events have been recorded in William of Tyre's accounts of Syrian gangbangs.

Person 3: 'Oh Shit! They just did a Brownill!!'
