,, Blind date" is when person goes on a date with someone he/she never met. This is shown in many reality shows.

Blind date is a social meeting between two people who have not met before. And yeah, I've had such experiences. Some ended good, and some... Well, if one day you'd want to try that, I would advise you to get a picture of the man/woman you're going to date, in case if you don't need any fails... like me, when I literally had to run away from my date, because to say the least, he wasn't good looking... x_x so be careful...

it means a person will have a date with another person who inttroduced by somebody ,and they wasn't met each other before.
