A woman who purposely draws attention to her large, round, meaty boobs. This is primarily done for male attention and there are no boundaries as to where the boobage is displayed (i.e. at work, kids birthday parties, funerals etc).
The titty mungo typically has a shrill or booming voice and cackles like a hyena in heat.
