A slouch hat is a type of wide brimmed bicorn/tricorn, usually made of felt or cloth. The slouch hat has been used by many militaries and police forces, but is most famously used by the Australian military, or ANZAC. They are commonly depicted with one side being bent, the reason being it allows the user to more easily access a rifle equipped with a bayonet without damaging the hat.
P1: Why is that guy wearing a slouch hat?
P2: He's probably military, or it's because the sun's out.
This is the given name to a certain position in which someone playing WoW (World Of Warcraft) will typically sit over the long preiods of time they play wow. The position is adopted by so many as it gives a much more comfortable feel to your position over long periods of time, and to make easier access to use of the keyboard. It has been known for books to be placed on the desk next to the keyboard to rest the arm in a certain position as part of this position.
For the best example(s) of the WOW slouch, I can think of off the top of my head watch the episode of South Park 'Make Love Not Warcraft'. or alternatively ask the biggest no lifer you know who spends their life on WoW to show you.
The Plumber's Slouch occurs when someone's pants and shirt separate, usually when a person is bent over... giving everyone a view of the person's butt crack... but Plumber's Slouch allows you to refer to the situation without being overly graphic.
Please wear a longer shirt under your sweater, so you can avoid Plumber's Slouch every time you bend over. No one wants to see that!
The call of the lesbian. If you see a quazi-tom boyfemalelurking about, check to see if she has the slouch, if so..she's a lesbian. If not back off she is not into chicks.
"Hey Kenny, I'm not a lesbian, I don't have the lesbian slouch."
