A vaginasseur is an expert judge of taste, look, smell, and feel of a vagina. This status of expertise is honorific and is typically acknowledged by one's "bros". Earning this title is typically done by being a known sexual deviant. Not only must you have had sex with many women, but you must have talked about each encounter in great detail, vividly describing each vagina to the point of exhaustion.
Tim sure is a sexaholic, he's had sex with at least three hundred girls and can recall every vagina in disgusting detail. I idolize the way that man can describe each fold. He is the ultimate vaginasseur with his keen vaga-analytic abilities.
