Angry Gus Poyet told the fans who booed Brighton at half-time against Watford to stay at home next week.
The Seagulls trudged off two goals down thanks to Sean Murray's superb free-kick and Troy Deeney's penalty.
But they rammed the taunts back down their disgruntled supporters' throats with a stirring comeback to peg Watford back to 2-2 thanks to a late leveller from former Hornet Will Buckley.
Brighton's hopes of reaching the play-offs are finally over, but Poyet feels the fact they were even in the hunt in their first season back in the Championship means the fans should cut his men some slack.
"The booing is not acceptable, I would like to tell them not to come if they don't like it, if they don't like the way we play, stay at home," said the Seagulls boss.
"There's something wrong in this football club, maybe it's time we told them what they can expect. I don't know the last time Brighton were in the top 10 of the Championship.
"There were too many things wrong tonight, too many on the pitch and off the pitch. But it's the first time I've seen a reaction like that from the stands.
"Maybe I should say it was a minority but I didn't like it. They are being unfair on an unbelievable group of players who have brought joy to this football club."
Brighton, looking to put Saturday's 6-0 drubbing at West Ham behind them, got off to the worst possible start.
Poyet handed a debut to goalkeeper David Gonzalez but the former Manchester City reserve's first task was to pick Murray's 25-yard cracker out of his net.
And Watford went two up shortly before the interval, Deeney netting from the spot after Ashley Barnes felled Jonathan Hogg.
But with the boos still ringing in their ears, the hosts pulled one back early in the second half through Inigo Calderon.
And Buckley, the £1million capture from Vicarage Road last summer, completed the comeback when he tucked in Vicente Rodriguez's cross.
"It wasn't easy for the players," added Poyet.
"There is no place to hide after a 6-0 defeat and then being 2-0 down at half-time but they put it right, they were brave and should be proud."
Murray's goal was his sixth in 12 matches, form which earned the 18-year-old the young player of the month award for March.
His manager, Sean Dyche, said: "He's a very talented young man who is enjoying his football which we have given him the freedom to do.
"He's got a nice manner about him, he works very hard and when you throw in his talent it's a nice mixture.
"We played to win in the first half. To go two up at Brighton, with their home record, and make them play it long at times is very pleasing."
