how to take grungy/vintage-y looking photos?

[tennis_tacos]

So I've been trying forever to figure out how people take those grungy looking photos as if the photo was taken with flash but it's more muted, the colors are faded, and the entire photo often looks kind of hazy/blue-ish? I figure it can't just be film photography, because the fad seems too common. Is it a specific type of camera (disposable/digital/point and shoot?), or setting on a camera?
I personally own Canon Rebel DSLR and have never been able to manipulate it to take photos that look like the following. Any help would be appreciated! Thanks.

Here are just some examples I found on tumblr of the *effect* I'm talking about:

A good way is to use a disposable camera and then scan the pictures into your computer. This is a resulthttp://www.facebook.com/?ref=tn_tnmn#!/photo.php?fbid=4566323429745&set=a.1592495725911.81998.1041439210&type=3&theater
Also you can get apps on ipone and probbable other iphones that can make it go vintage.
try cameras that are old and not good quality, canon cameras are probbably to good quality to do this.
Disposable camera is the best way x

I will never understand why you WANT to take such awful, amateurish looking photos? There is nothing "grungy / vintage" about them. They are simply awful photographs taken with awful cameras by awful button pushers.

I agree with the above answer. Your Canon DSLR has decades of technology in it's design to do all it can to NOT take such photos as in your examples. Quit trying to dumb it down. Sell it if all you want is such terrible photos.

Just go out and buy any cheap, disposable camera hanging on a rack at a check out counter, one with a built in flash. Get the film developed at the cheapest place you can find, and get the cheapest, lousy quality scans available at time of processing.
