A ungainly, stupid, clumsy ill mannered and loud adolescent. Use in Ireland derives from the African tribe the Baloobas who were involved with clashes with Irish UN Peace Keeping troops in the Congo in the late 20th century. Often prefixed with "Big".
You big balooba! Look what you've done!
The skin between your nostrils.
Hey Dave, my balooba is pretty sore. Maybe I should stop picking my nose.
