Under boob

[Britney]

The awkward amount of breast protruding from beneath a bikini top. It is debatably sexy, but it is def a spring break must.

[Couch Potatoe]

The under boob is very ellusive and rarely shows itself. To coax, said the under boob from hiding, one must adjust thine own bra to a point of maximum comfort. The constriction of the bra causes under boob to show underneath the restricted area pleasing those around, that in which interns to show gratitude shall rejoice in joyfull song and dance;giving it the title, UNDER BOOB.
