Sean Lamont has called for Scotland's players to come together for an "honesty session" following the Six Nations defeat by Wales on Saturday.
The Scots lost 24-6 against Wales, following on from a 34-21 defeat in France seven days earlier and now lie joint-bottom of the table with Italy.
"It was abysmal - the boys need to go away and have a look at themselves," full-back Lamont said.
"I'm sick of it - I want to win something, I really do."
With matches against Ireland on 27 February and England away on 13 March to come, Scotland face the prospect of a wooden spoon play-off against Italy on 19 March if results do not improve.
We need to have a closed-door session and we need to look at each other and say: 'Guys, if you don't want it, don't be here. Somebody else will fill in'
"The players owe it to the coaches and the fans," Lamont added.
"We need to have a closed-door session and we need to look at each other and say: 'Guys, if you don't want it, don't be here. Somebody else will fill in'.
"I'm sick of having this year after year, valiant losers or whatever.
"We need to pull our fingers out, there's been too many years gone by where we've been also-rans. It's not good enough."
Prior to the 2011 Six Nations, Scotland had beaten Australia, Ireland, Argentina twice, South Africa and Samoa in just over 12 months, so the capitulation was arguably the worst of coach Andy Robinson's era in charge.
Lamont, who replaced Hugo Southwell after 20 minutes after the full-back took a blow to the face, was one of Scotland's few players to perform, making numerous breaks and a try-saving tackle on Wales centre Jamie Roberts.
And the Scarlets back, who can play full-back, wing and centre, is upset at being left out of the first XV when those occupying starting places are under-performing.
He continued: "I've had a tough two weeks not being picked and I've come on in the last two games and I've had a point to prove and hopefully I've proved that point.

"I think every one of our boys needs to be looking over their shoulder because the performances, bar a few, were simply not good enough.
"I think we need to get in, have a sit down, closed doors, no coaches, just players - we need to do some finger pointing and soul searching.
"It's one of those things that needs to be done, it needs to be sorted out.
"We can't have teams coming up here and doing that to us."
Scotland were 13-0 down when Lamont entered the fray after conceding an early try for the second successive week.
James Hook, who was selected at fly-half for the first time in two years, scythed through a gap and popped the ball to Shane Williams to score after eight minutes.
Hook kicked 14 points before Williams completed the victory with his 53rd try in 77 Tests, touching down following Jonathan Davies' kick through.
All Scotland had to show for the 80 minutes - in which they had the better of possession and territory - was two Dan Parks penalties and the hosts scored only three points in six first-half minutes when Wales were reduced to 13 men by the sin-binning of Bradley Davies and Lee Byrne.
"The most embarrassing thing was they were down to 13 at one point and we didn't convert," said Lamont.
"It's not good enough. We need to pull our fingers out, without a doubt."
Robinson is certain to make changes for the visit of Ireland, with Lamont among those who could be promoted to start.
We let Murrayfield down - Robinson
Moray Low is almost guaranteed to come in at tight-head prop, with Euan Murray unavailable due to his religious beliefs preventing him from playing on Sundays.
The 2009 British and Irish Lion's performances in the two opening Six Nations games may have led him to be dropped anyway.
Second row Richie Gray, who was Scotland's star in Paris, is also set to return after missing Saturday's game through illness.
More personnel changes could follow, with Johnnie Beattie likely to come into contention for the first time since last June's tour to Argentina following a lengthy absence as a result of shoulder surgery.
Eleven Scotland players suffered injuries, with Southwell requiring stitches to his face.
Also requiring treatment were Max Evans, Joe Ansbro, Nick De Luca, Mike Blair, Richie Vernon, Kellock, Kelly Brown, Murray, Low and Ross Rennie.
