(Acronym taken from: WordsOverheard.com)
You: "WOH lady, you're freak'n retarded!"
If said "hot" persons are not realizing their full potential in careers that do not cater to their assets, they are considered a "WOH". Acceptable careers include male stripping, lifeguarding, personal trainer, Hollywood beefcake acting with an allergy to shirts.
Likewise, if a "hot" person is just sitting there, not applying oneself to spreading the hot, showing/and/or sexing it around, they are squandering their potential, hence, "WOH".
A.) You see a really hot dude, amazing body, great smile- But, as soon as he opens his mouth is so stupid and boring that he's a "WOH".
B.) Brad Pitt in "Tree of Life". Totally Waste Of Hot. He should always be in just shirtless movies (see: Legends of the Fall). Examples of persons who have done this correctly are Alexander Skarsgard in "True Blood", and Michael Fassbender in "Shame". Bravo, gentleman, bravooooo.
