Does anyone know what I mean?
When people are not genuine. Of course, extends to both genders, but at the moment I'm online dating and see so many men who seem great but when you meet them, you just cringe a bit because it feels like they're putting on a huge act?! Try-hards essentially 
Don't get me wrong, I'm far from perfect, but really hate when people are putting on a front. Anyone know what I mean?!
