According to a survey by the British dating site uk.parsnip.com, your Facebook and Twitter account could be the deciding factor when trying to close the deal on a potential date.

Nearly two out of three single people, 65%, say that they check someone out on social media before agreeing to go out on a date with them.

And three in four people who've checked out a potential date found something that CHANGED THEIR MIND.  Here are the five things on your profile that are most likely to cost you a date:

1.)  A bad profile picture.
2.)  Having no sense of humor.
3.)  Aggressive online behavior.
4.)  Flirting with other people.
5.)  Oversharing.
