Three's a party

[greenisgood]

When do you say "Three's a party"? Does it convey any negative or wry sense?

I guess the author who said "But I always say, one's company, two's a crowd, and three's a party", meant the more people in a gathering the better it is?

I've always heard:

Two's company. Three's a crowd.

Of course, there's The more the merrier.

Two's company. Three is a crowd.

Meaning, usually, that a boy and girl want to be alone but there is a third party present.

For some reason the 3rd party is 'playing gooseberry'. I expect the explanation is just a click away.
