a circular structure in a student center where many bro's gather in between classes, meals and other social obligations. When lacking a proper representation of bro's, the Brotunda is mistakenly referred to as a Rotunda. The Brotunda was founded at Quinnipiac University.
Wow, look at all the bro's in the brotunda lounge.
Rotunda my ass, this is a Brotunda.
