There are two 'viral' titles, Infected and STD. If someone using the Infected title in their callsign knifes you, then it 'infects' you and unlocks that callsign title on your profile.|
STD is the opposite, it's transmitted to the stabber from the stabbee.
edit: are you sure it didn't unlock the infected title? It's one of the zombie head ones.
