An alternative to the traditional forward posture while sitting on a toilet, in which a person sits facing the back of the toilet as opposed to facing outward. The advantages of this position include arm rest while reading, space for resting computers, books, alarm clocks or coffee mugs, and ease of access to the toilet in case of malfunction. The only known disadvantage is the need to remove ones pants or to have a reinforced towel rack to allow for the south paw swing.
Andrew: Damn dude you were in there for so long.

Bruce: Yea man, I was sitting southpaw and was just too comfortable.

Alex: Do you have to take off your pants to sit southpaw?
Bruce: Nah, just give it the ol south paw swing.

When a handshake is offered but your right hand is busy - such as while holding two beers or perhaps you're wearing a cast. Your only option is to shake with your left. If handled correctly, it comes off more as a low-five instead of an awkward hand-holding moment between two dudes.
When I turned, Dave had his hand out for a shake. He didn't see me holding my niece's hand, so I gave him a Southpaw Shake with my free one. No gayness.

Guy 2: Why am I friends with you?

What happens to left handers when they write a lot in pencil or pen. The bottom of their hand smudges from the graphite or ink as their hand passes over what they just wrote on the paper.
