Chrissy Teigen -- Rips Edelman's Tinder Chick ... 'It's Stupid, Ridiculous'

Supermodel Chrissy Teigen is coming out swingin' against the woman who shot a pic of a sleeping Julian Edelman and posted it to Tinder ... slamming the whole thing stupid and ridiculous.

The woman who snapped the shot, Sabrina, has already been blacklisted from Boston nightclubs by people who feel she shamelessly violated the New England Patriot player's privacy.

And Wednesday at The Grove in L.A., Teigen told us the problem is bigger than it seems -- "A lot of chicks do that sh*t. It's so ridiculous."

Teigen explained, "Everyone's a little too proud nowadays. I think these girls should relax a bit."
