A former star player for the New England Patriots has been threatened with a lawsuit by delusional parents who claim he's ruined the lives of their kids by exposing a drug/alcohol fueled party at his home.

Brian Holloway tells TMZ, "I blew way past furious" when he discovered several hundred teenagers broke into his vacation home outside Albany, NY over Labor Day weekend.

The kids started tweeting and Instagramming madly inside, posting photos of what looked like a scene out of "Animal House."

Holloway went ballistic, created a website -- helpmesave300 -- and started posting pictures of the damage, as well as the tweets from some of the partygoers -- and those tweets ID'd the kids.

Holloway tells TMZ ... he's been told by the Sheriff's Dept. some of the parents are furious because their poor kids have now been exposed. Some bitch that it will hurt their chances of getting into college. Others whine their poor kiddies are being harassed at school. And they actually have the audacity to threaten a lawsuit.

Holloway says there was plenty of evidence of drugs at the party, including crack and meth. And, of course, a river of alcohol.

He says it's gonna cost $20 - $40k to repair the damage.
