Literal Italian translation is "good pussy." This term should be used when talking about girls when in their presence. If you don't want to blunt and talk about how hot some bitch is...just say she's a buona figa.
In Call of Duty : World at War, when you have a bayonet attached to your weapon, and martrydom perk equiped. You go in to bayonet someone, and they shoot you, then your G nade (martrydom ) drops and killed that player.
