I know we've all said yellow teeth umpteen times, but lately I've been watching lots of reality dating shows and even when the teeth are mostly white but the canines are yellow, it just gives me the ick straightaway. I can't unsee it, it's like looking at someones nasty foot in their sandal in the checkout line, like you want to look away but you can't. Why am I like this, I actually feel a bit petty and wrong lol.
Otherwise, another big one is wiping the sides of your mouth with your hand, like where you can tell a collection of something was wiped off.
Guys with food stuck in their teeth and they don't know.
Something stuck in the corner of their mouth and they don't know.
Those are big ones for me, not coming back from that.
