A generally lower class person living in the right handed world. Characteristics include: general goofiness, outlandish in their actions, their penis hangs to the opposite side (I'm serious ask a lefty), and they have sex differently.
Why is that guy over there drooling and speaking incoherently?
An undesirable female (or male). The term is derived from swiping left on the Tinder app to reject a female (or male) you don't want to be matched up with.
Nah dawg- she's a lefty fo' sho'. Swipe left homey!!
