Large Breast on that of the human species, male of course thus the M .. Defined by a boy of the name Rubbo who has these large chesticles in that area.. He is ashamed of them and always wears more than one layer of clothing on his upper body.. usually with a beater.. he will never go into a pool.. EVER
Eddie refused to come into the pool because he would thus be embaressed by the MuBBos he was hiding.
The Rubbo boy from down the steet has some real boobies on him don't he, they should call him MUBBO.
Eddie has some big Mubbos.
