The teardrop tattoo or tear tattoo is a symbolic tattoo of a tear that is placed underneath the eye. The tattoo can have various meanings: it can signify that the wearer has killed someone or has spent time in prison; that the wearer was raped while incarcerated, having been tattooed involuntarily, or it can acknowledge the loss of a family or fellow gang member. Sometimes, only the wearer will know the exact meaning of the tattoo. The tattoo’s meaning also can change depending on whether the tear is empty or is filled with ink. 
The tattoo is sometimes worn by the female companions of prisoners in solidarity with their loved ones.
