A Talimancer is a wild, rabid beast which is commonly encountered on the Bioware Social Network. They are unique animals since they are the result of an unfortunate occurence where a perfectly logical male gets infected by the Talimancus Romancus virus. This turns the human being to a drooling beast which crusades against everyone and everything who doesn't want to fuck Tali, or find out what her sweat smells like. Talimancers are pack animals who group together, and they prey on anyone who doesn't like Tali.
If you encounter one in the wilds, the best course of action is to ignore it. However, if it is aggressive and tries to come at you, play dead. If you fight back, the beast will call it's pack to help him, and then you are fucked.
It started off as an analysis of Tali's sweat, trying to figure out what it'd smell and taste like. I quickly realised that most scents originate from bacteria, which would be minimal to non-existant for quarians.
The next best thing, would be urea. Urea is essential for the metabolism of mammals, and also a bonding agent (For say, p-cresol and o-cresol, two odor chemicals found in sweat. Though these likely aren't available to quarians), and it, and residues of the amino acids and chemicals used in its production are excreted through many different ways. Urine, sweat, etc.
