-Tinderella (n.): a female Tinder user. I'm basically an unpaid professional Tinderella.
-Tinderho (n.): abbr of Tinder Whore; usually female, but probably could be male, Tinder addict. Someday I'll realize that it's maybe a bad thing what a fucking Tinderho I am.
-Left-swipe / Swipe-left (v.): to reject a potential Tinder match, clicking the X signifying "nope" or physically swiping the person to the left side of the screen. Ew I left-swiped him without even thinking about it.
-Right-swipe / Swipe-right (v.): to "like" a person on Tinder by clicking the <3 or to physically swipe the person to the right side of the screen. Oh he's attractive, I think I'm gonna right-swipe him and see if we match!
-Match (v.): to Tinder-like someone who likes you back. We obviously matched.
Um those are the only words I can think of right now. They're the essentials at least.
