What does Bowie bulge mean?

Bowie bulge meaning in Urban Dictionary

An obscenely prominent and hard-to-ignore bulge in the crotch area of a male's clothing.Originates from the motion picture Labyrinth, where stone legend David Bowie plays the Goblin King, dressed in a skin-tight spandex catsuit that totally doesn't hide his genitalia. This can be made all the more uncomfortable because of the undeniable fact that his character materialises in a teenage girl's room and steals the woman child sibling.
