She's/He's hot but you can't see going any further
 

You meet a chick or a dude who happens to be hot, but when you go on the first date, how long does it take you to know that this isn't going to go anywhere? What is it about their personality that would really fuck things up? If she's stupid, I can usually see that within the first 10 minutes. I'll probably still want to score, but I won't take any further than that.

Lol! If a guy has nothing going for him its a major turn off... I cant be in a long term relationship with someone who isnt at my level or higher when it comes to work and school at the minimum......That info should be disclosed within the first half hour or sooner... but shyt if he's hot we'll see wassup... nothing serious would ever work tho

Honestly I usually don't even need the first date to know. It's pretty easy to tell if someone is completely wrong for you right off the bat, and no amount of pretty makes up for it.
