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."
Tim: "Yo Sam, tuck that Under Boob away, you're giving me a boner!"

Sam: "Oh man, I apologize Tim, I constricted my bra to a maximum, and it just well, popped out!"
