Bronaise

A substance that a certain subset of Weight Lifters ingest to increase muscle mass. Bronaise is created by rapidly stroking another man's penis and swallowing the ejaculate. Bronaise can only be attained from another man, and must be fresh to work.

Jeff's gained 20% muscle mass over the last few weeks using massive doses of Bronaise. He's ripped!

Bronnaise 

The filling within a bromance sandwich; it's bukkake for best bros.

"The bronnaise was thick, like a gooey high-five."
